Top 10 Best Sibling strollers of 2021

How we did the test

Our tests are independently conducted and reflect the test editor's honest and objective opinions. Selection of products and test results are in no way influenced by manufacturers, retailers or other internal or external parties.

We carry out our tests ourselves and test all products as they are intended to be used in reality. In our test of sibling strollers, we asked ordinary families and experts in the area to use the strollers with their own children. Our testers used these strollers with both babies and larger children, to assess how long the stroller can be used for. The sibling strollers we tested were both side-by-side and tandem strollers. And we tested them with carrycots and seat units. The strollers were used in an urban environment and on slightly rougher terrain.

  • Qualities: In which ways can the seat units and carrycots be configured on the stroller, can you attach a baby car seat, can the stroller be transformed into a single child stroller?

  • Functions: Are the seat units reversible, are they normal or ergonomic, is there a lying position and is the handle adjustable?

  • Use: What’s the stroller like to push on different surfaces, is it narrow enough to work on public transport, can it easily be folded and is it small enough to go in a car, is it comfortable to sit in for the child?

We place particular importance on the size and weight of children who can ride in the sibling stroller, so that it’s primarily your needs rather than the stroller’s maximum size and weight limits that determine how long the stroller can be used. As well as these characteristics, we also assess the general quality of the bicycle trailer together with how its functions and characteristics relate to its price tag.

1. Bugaboo Donkey 3 – BEST CHOICE SIBLING STROLLER

High quality and adaptable sibling stroller that’s fantastic to push and has intelligent accessories

Max. weight lying/sitting: 9/22 kg Width: 74 cm Type of seat unit: Ergonomic Includes rain cover/apron: Yes/no Adapter for baby car seat: Yes Wheels: Puncture-free Handle: Telescopic Converts to single stroller: Yes Reversible seat units: Yes

Bugaboo Donkey 3 Duo

The Bugaboo Donkey 3 is two strollers in one. Thanks to the width of the expandable chassis, you can convert the Donkey 3 from a 60 cm wide single stroller (mono) to a 74 cm wide sibling stroller (duo) in just a few minutes. And together with Bugaboo’s really clever standing board, this means you can easily push three children with just one stroller. The Donkey 3 has a very wide range of intelligent and pretty much essential accessories – everything from specially designed footmuffs and practical cup holders to particularly airy hoods for hot summer’s days.

Ergonomic seat units with lying position and long hoods

As a sibling stroller, the Donkey 3 can be used both for twins and for siblings of different ages. You can combine two carrycots, one carrycot and a seat unit or two seat units. You can also attach one or two baby car seats to the chassis using the correct adapters. The Donkey 3 has a carrycot that’s relatively spacious for a sibling stroller. It comes with a removable mattress and a cover.

The seat units are ergonomic and can be angled backwards between sitting position, reclining position and lying position. Forward-facing there’s only a sitting position and reclining position. To change position, you undo the catch on the back of the backrest with one hand. The harness on the seat unit is really intelligent, with separate straps that you click into the buckle one by one. The Donkey 3 has the same hood for the carrycot as for the seat unit. It’s extendable, and fully extended gives excellent shade over almost the whole of the child. One new feature on the Donkey 3 is that the hood now has a peephole and ventilation hatch with a fold-down cover.

Narrow enough sibling stroller with easy-to-adjust handle

The basket under the Donkey 3 is relatively spacious, but a bit inaccessible when you have a carrycot on the stroller. If you’re pushing the Donkey as a single stroller, the second seat unit/carrycot is replaced with a side basket. The basket underneath expands with the chassis when it’s pulled out. The Bugaboo Donkey 3 has a telescopic handle that you need to use both hands to height adjust, but which can be set to everything from very low to very high. Regardless of how tall you are as a parent, you can walk comfortably behind this stroller.

It’s very useful that the Bugaboo Donkey 3 is less than 75 cm wide. This means that accessibility when pushing the stroller is very good – lifts, public transport and standard width doors aren’t any problem at all. The puncture-free, foam-filled wheels are a little narrower than on the previous version, but they still roll very well. It’s almost shocking how easy it is to steer the Donkey 3. The stroller can be manoeuvred with one hand even if you have two children in it.

One of the best sibling strollers you can get with reversible seat units

Compared to its predecessor, the Donkey 2, the most in demand improvement in the Donkey 3 is that the seat units now have swing-away safety bars. This makes it much easier if you often have to put your children into or remove them from the stroller. The maximum weight for the seat units is 22 kg, but one disadvantage with the Donkey 3 is that in single mode with the seat unit facing backwards the maximum weight is only 15 kg. In all other modes, the higher maximum weight applies.

There is currently no other sibling stroller that’s as adaptable and versatile as the Bugaboo Donkey 3. The price is high. But for your money you get a very long period of use, loads of clever functions and essentially unbeatable manoeuvrability. In addition, Bugaboo’s strollers generally have good second hand value, so a lot of what you spend now you’ll get back in the future. The Bugaboo Donkey 3 isn’t a perfect sibling stroller. But it comes very close to it.

2. Baby Jogger City Mini GT 2 Double

Spacious sibling stroller with good lying position, adjustable foot rest and convenient folding mechanism

Max. weight lying/sitting: 9/23 kg Width: 75.5 cm Type of seat unit: Normal Includes rain cover/apron: No/no Adapter for baby car seat: Yes Wheels: Puncture-free Handle: Knee-joint Converts to single stroller: No Reversible seat units: No

Baby Jogger City Mini GT2 Double

Baby Jogger's City Mini GT Double sibling stroller has long been popular for its successful combination of spacious seat units and compact folding. Now it’s been updated, and the Baby Jogger City Mini GT 2 Double is noticeably better than its predecessor.

The City Mini GT 2 Double is a side-by-side sibling stroller with two seat units that are fixed forward-facing. If you want to use the stroller from birth, there’s a rear-facing carrycot you can buy separately. You can also attach a baby car seat to the City Mini GT 2 Double, but only to one seat unit at a time. In other words, this isn’t the best choice of sibling stroller for twins. After your child has outgrown the small but cosy carrycot, you have to turn them to face forwards.

Parents of small children often praise Baby Jogger’s strollers for their long period of use, which is made possible by high maximum weights and spacious seat units. And the City Mini GT 2 Double is no exception. A normal-sized 5-6 year-old can travel comfortably in the stroller. The backrest is high, but unfortunately the hood takes up some of the space around the child’s head. Widthways there’s plenty of space in the seat area.

The seat units in the GT 2 Double can be adjusted steplessly down to a good flat lying position. However, the sitting position is slightly backward-leaning, even if you try to push the backplates forwards. The stroller’s new covers feel cosier, but it’s actually the fact that the City Mini GT 2 Double now has adjustable footrests that really increases comfort for the child. The advantage of the footrest is that the child can sleep in a more stretched out position. The disadvantage is that it requires quite a lot of force to release the footrests and to push them into place.

The harness in the seat units of the Baby Jogger City Mini GT 2 Double is easy to adjust for height and circumference. You can easily take it apart into separate straps, if you want to add a footmuff. Unlike the older version, the City Mini GT 2 Double now has separate safety bars – one per seat unit. The hoods give good protection against sun and wind when they are fully extended. There are two peepholes in each hood, so you can have good contact with your child as you walk.

The stroller is very nice to push. The GT 2 Double is a stroller you can load with heavy baggage in the spacious but slightly accessible basket, and with children. And yet the sibling stroller still rolls happily along. The foam-filled wheels can cope with gravel paths as well as snow and uneven grass, and the fact that the BJ City Mini GT 2 Double now has good suspension and the chassis makes the ride even smoother.

The sibling stroller has also retained its incredibly convenient folding mechanism. With one hand around the strap in each seat unit, you simply lift straight up and the GT 2 Double folds in the middle and locks itself automatically in folded position. The old GT Double was popular for many years, and everything indicates that the new Baby Jogger City Mini GT 2 Double will be at least as popular for at least as long.

3. Cybex Gazelle S

Convenient and extremely adjustable lengthways sibling stroller with normal seat units

Max. weight lying/sitting: 9/22 kg Width: 65 cm Type of seat unit: Normal Includes rain cover/apron: No/no Adapter for baby car seat: No Wheels: Puncture-free Handle: Telescopic Converts to single stroller: Yes Reversible seat units: Yes

Cybex Gazelle S (Duo)

The Cybex Gazelle S is a lengthways sibling stroller uniquely equipped with normal seat units, which can be angled to a flat lying position. The stroller is 65 cm wide, only slightly wider than a normal sized duo. The Gazelle S can easily grow with your family. One child, two children, twins – the Gazelle S works for most combinations.

Nice to push but best suited to smooth surfaces

With the Gazelle S you can attach both a carrycot and a baby car seat and a seat unit. There’s also an extra shopping basket for those who really want to be able to get a lot of shopping while out with the stroller. The chassis is sturdy and stable, even when the stroller is heavily loaded. The puncture-free wheels roll easily and the Gazelle S is generally smooth to steer.

If you use the stroller as a sibling stroller, however, the distribution of weight is crucial for how easy it is to push. With a heavy child at the front, the Gazelle S tends to be sluggish and can pull to the side when the ground slopes. This is partially remedied if you lock the front wheels. With two larger children, of course, the stroller is also heavier to lift over kerbs.

The Cybex Gazelle S isn’t an off-road stroller. It’s true that the chassis has suspension and you can push it on gravel paths, but the stroller still feels a little bumpy on uneven surfaces. If you mainly walk on asphalt and pavements, accessibility is very good.

Many possible combinations

There are two attachment points on the chassis. The upper attachment point can be adjusted to three different height positions, the lower one can be rotated forward if necessary. Different positions should be used for different combinations of baby car seat, shopping basket, carrycot and seat unit. The seat units also have different maximum weights (15 or 22 kg) depending on where they’re positioned and how they are turned.

This means there’s a lot to keep track of to use the Gazelle S correctly. Cybex have anticipated the risk of confusion and permanently attached a guide in the basket. This is extremely practical and is something you often need when you’re reconfiguring the stroller.

With the Gazelle S you can choose between many different ways of attaching the seat units. Both children can face backwards, both forwards, one in each direction – everything is possible (although as we’ve mentioned, the maximum weight varies). However, you need to be aware that what works in theory isn’t always as good in practice. For example, if you want to have both seat units in full lying position, only a few combinations work.

Reasonable period of use and easy folding

The seat units have backrests that can be tilted from an upright sitting position down to a flat lying position, and can be used with a soft carrycot in. The seat unit is normal in size for a sibling stroller. Even if the seat units (in the right position) take 22 kg each, your child has probably grown out of them in terms of height before that. Above all because the footrest is quite short.

For children up to 3-4 years old, the Gazelle S works well. Larger children can travel in it, but they will have to sit with their legs bent. The hood has a ventilation hatch, can be raised on the seat frame and is extendable, but feels slightly short in lying position. The carrycot is snug and has smart memory buttons that make it easy to release.

The Gazelle S has an adjustable telescopic handle and generous legroom for the adult pushing it. The shopping basket is very spacious, but if you use the stroller with two children, some of that will be taken up for legroom. A big plus with the Cybex Gazelle S is that it can actually be folded with the seat units on the chassis. This means that when folded it’s exceptionally compact for a sibling stroller.

Convenient sibling stroller with good sleeping comfort

The Cybex Gazelle S is best suited for the family who want to easily adapt the stroller to their daily needs. It’s particularly suitable for anyone who often packs the stroller in the car, or who lives in a small home and doesn’t want a wide stroller taking up space in the hall. It’s most comfortable to push in urban environments or on asphalt.

If you want a lengthways sibling stroller but want to still be able to offer your children good sleeping comfort on a flat surface, then the Cybex Gazelle S is undoubtedly the best option on the market.

4. Baby Jogger City Select Lux

Easily adapted tandem sibling stroller that has many intelligent accessories and functions

Max. weight lying/sitting: 9/20 kg Width: 62 cm Type of seat unit: Ergonomic Includes rain cover/apron: No/no Adapter for baby car seat: Yes Wheels: Puncture-free Handle: Telescopic Converts to single stroller: Yes Reversible seat units: Yes, separate

Baby Jogger City Select Lux

The City Select is a model that’s been in Baby Jogger’s stable of strollers for a long time, and the City Select Lux is the updated version. Compared with its predecessor, the Lux is even smaller when folded, has better suspension and a different handle shape The seat unit is the same as on Baby Jogger’s Premier single stroller model, and has softer, cosier upholstery. The City Select Lux is a single stroller that can be expanded to a tandem sibling stroller. You can combine seat units with carrycots with baby car seats in endless combinations. One function of the Lux that stands out a little extra is the jumpseat that you can buy separately. This is a seat unit with a harness and footrest, but without a backrest, that you install on the chassis. It’s like an advanced standing board – perfect for children who perhaps don’t want to walk but don’t need a standard seat unit either. What’s really clever is that you can attach a carrycot or seat unit above the jumpseat and quickly change between having one and two children in the stroller by moving the parts around.

The Baby Jogger City Select Lux has an adjustable telescopic handle and an easily accessible handbrake. The shape of the handle is comfortable, but the handbrake takes up too much space for it to be entirely comfortable to keep your hands centred. The four wheels are all puncture-free and easily cope with a bit of uneven terrain and quite a lot of snow. The front wheels can be locked but you really need to do this. The chassis is on the longer side. You can travel on the bus OK with the Lux when it’s a single stroller. But if you've got two seat units or carrycots on the stroller, it’ll stick out quite a long way into the gangway. The basket is big, and there’s plenty of space left even when the Lux is being used as a sibling stroller. As a single stroller, it’s fantastic to pack, particularly if you buy Baby Jogger's own shopping basket as an extra.

The seat unit on the Lux is spacious, with an adjustable footrest and a hood that can be attached to the frame at two different heights. The seat unit can be inclined down to a good lying position using a catch on the back of the backrest. Of course the seat units are reversible – but the stroller is easiest to push if the front seat unit is turned towards the person pushing. You can fold the City Select Lux in a single piece with two seat units on, and the stroller becomes impressively flat. It’s nice to push. Even though you could get more lift from the handle when pushing a stroller with two children, it still works OK. There are many advantages with this type of sibling stroller, and the Baby Jogger City Select Lux offers so many different configurations that it’s almost impossible not to find one you're happy with.

5. Baby Jogger City Tour 2 Double

Spacious and easy to push sibling stroller with full lying position and very compact folding

Max. weight lying/sitting: 9/20 kg Width: 66.5 cm Type of seat unit: Normal Includes rain cover/apron: No/no Adapter for baby car seat: Yes Wheels: Puncture-free PU wheels Handle: Not adjustable Converts to single stroller: No Reversible seat units: No

Baby Jogger City Tour 2 Double

With the Baby Jogger City Tour 2 Double, double strollers take a big step forward. This is an ultracompact sibling stroller that can be used both during your everyday life and when you’re travelling. At just 66.5 cm wide, it's narrow enough to go through every door and even many smaller lifts. Folded, the Baby Jogger City Tour 2 Double measures a very compact 63 x 66.5 x 25 cm.

The Tour 2 Double can be used direct from birth if you buy a carrycot. You easily attach it to the chassis with adapters. You don’t need to remove the seat unit fabric beneath it, which means you can quickly change between having a baby and a larger child in the stroller. The two seat units are fixed in a forward-facing position. The backrest can be inclined steplessly from an upright sitting position down to what’s almost a flat lying position.

The child’s sitting position is comfortable and there’s a surprising amount of space in the seat despite the stroller being so narrow. Children up to 4-5 years will be comfortable in the Tour 2 Double. Both seat units have adjustable footrests. This means the lying area is longer and the child can sleep comfortably in the stroller. The sunshade is OK, even though the hoods could have been still longer. On the back of the hoods are peepholes in mesh fabric, which also let in the air. These are attached with Velcro, and can be rolled out of the way and secured with an elastic strap.

The Baby Jogger City Tour 2 Double has puncture-free PU wheels. These are very small but roll pretty well. This isn’t a stroller for going off-road with – the Tour 2 Double is best in an urban environment and on smooth surfaces. The brake by the right wheel is easy to apply but very difficult to disengage. Not at all straightforward if you’re wearing sandals. The basket is very spacious, and easily holds everything you need for a full day out. Folding the City Tour 2 Double is child’s play. You activate a catch with one hand and press a button on the handle with the other. The stroller begins to fold up, and then you lift it by the folding straps in the seat units. Once folded, the Tour 2 Double is locked with a catch. As the stroller weighs 10.5 kg, you can easily load it into the car, and it fits even the smallest of boots.

The European maximum weight is 15 kg per seat unit, but Baby Jogger have tested it with 20 kg per seat. But the larger the children, the more difficult it is to push the stroller – which course is difficult to avoid giving the light construction and small wheels. But overall this is an extremely impressive sibling stroller. And if you want a travel stroller for two children, the Baby Jogger City Tour 2 Double is undoubtedly one of the best available options.

6. Mountain Buggy Duet V3.2

Narrow sibling stroller with sturdy wheels, full lying position and possibility of a rear-facing seat unit

Max. weight lying/sitting: 9/18 kg Width: 65 cm Type of seat unit: Normal Includes rain cover/apron: No/no Adapter for baby car seat: Yes Wheels: Air/puncture-free Handle: Knee-joint Converts to single stroller: Yes Reversible seat units: Yes, the carrycot can be reconfigured into a face-to-face seat unit

Mountain Buggy Duet V3

The Mountain Buggy Duet is a sibling stroller that’s been around for many years and is continuously updated. It’s now available in two versions – the standard Duet V3.2 from 2019, and the Luxury collection Duet Herringbone. The latter is a more upmarket version, with a completely black chassis, leather details and herringbone patterned upholstery. The functional difference is that the Duet Herringbone has puncture-free tyres. The Duet has received an update to the carrycot, which now has slightly tougher nylon upholstery. But only the Herringbone has new, improved fabric on the hoods.

The Duet is a sibling stroller that’s only 65 cm wide, with the fixed, forward-facing seat units placed side-by-side. If you want to use the sibling stroller with a baby, you have to buy a carrycot. This is small and narrow, but it works for the first few months. After this you can reconfigure the carrycot into a rear-facing seat unit, called face-to-face. New for the Duet V3.2 in 2019 is that the face-to-face seat unit has been improved with a deeper seat area and more positions. You can now change between sitting, reclining position and lying position.

To incline the rear-facing seat unit, you must remove it from the bracket and then pull it into the desired position. This isn’t particularly convenient. But it makes it possible to have your child facing towards you for longer, which is an obvious plus.

The Duet’s seat units have backrests that can be inclined steplessly down to a flat lying position. Some of our test children disliked the slightly backward-leaning sitting position. There’s a small footrest you can pull out which extends the lying position a little. And there's a built-in footrest in the chassis. The hoods give acceptable shade from the sun, and the harness is easy to use as it can easily be divided into five separate straps. You can buy a safety bar for the Duet which works for both seat units at the same time.

The handle has an adjustable knee-joint mechanism, and there’s also a handbrake on the left hand side which is very useful when you’re going down hills with a fully loaded stroller. On the back of the stroller there’s also a standard foot brake. The basket is relatively spacious, and has storage pockets both on the sides and back. You can fold the stroller up in one piece, and this makes it quite flat.

The MB Duet is quite bouncy to push, and the wheels (both the puncture-free ones on the Herringbone and the pneumatic ones on the standard Duet) can cope with quite a lot of snow and some rougher terrain. But the stroller is also convenient in an urban environment, thanks to its narrowness. The Duet’s main disadvantage is that the width also means less space in the seat units, but a normal-sized 4-5 year-old still fits OK. If you need a sibling stroller that’s compact, the MB Duet becomes a better option for every update it gets.

7. Thule Urban Glide 2 Double

Functional sibling stroller with spacious seat units that feels great to push

Max. weight lying/sitting: 9/22 kg Width: 79.5 cm Type of seat unit: Normal Includes rain cover/apron: No/no Adapter for baby car seat: Yes Wheels: Pneumatic Handle: Knee-joint Converts to single stroller: No Reversible seat units: No

Thule Urban Glide 2 Double

The Thule Urban Glide 2 Double is a side-by-side sibling stroller with two spacious seat units. The stroller can also be used with a carrycot, and you can buy adapters to attach a baby car seat to the chassis. The seat units are only forward-facing and have a slightly backward leaning backrest in sitting position. This can then be folded down to a flat lying position. When the child is sleeping in the stroller, you can open up the ventilation hatch by the child’s head to make it cooler. The hood gives good shade from the sun and has a combined ventilation hatch and peephole. The seat unit has Thule's convenient and well padded harness, which is easily adapted to the child’s size. There’s no adjustable footrest, but the chassis is designed for the child to have comfortable support for their feet. The size of the backrest and the space under the hood is enough for a normal-sized four-year-old to sit comfortably.

The stroller measures just under 80 cm wide. In other words, it will fit through standard doors but feels rather bulky and broad inside food shops. But the Urban Glide 2 Double feels more like it’s built for long walks on broad paths or for jogging along running tracks. You can run with the stroller if you lock the swivel front wheel in its fixed position. The fact that the stroller only has three wheels may look unstable, but the Thule Urban Glide 2 Double is well balanced and the large pneumatic wheels together with the suspension mean that it rolls very well. Gravel paths, bumpy surfaces, grass – accessibility is never a problem. The stroller is also easy to steer and comfortable to push thanks to an ergonomically designed knee-joint handle. In the middle of the handle is a practical handbrake, and on the back of the chassis there’s a standard foot brake.

Despite its size, the Thule Urban Glide 2 Double is convenient to fold. You lift part of the upholstery that covers the foot end of the stroller, which reveals a blue catch that you pull out to the side and twist. You can easily fold it with one hand, and the stroller becomes flat. It becomes even smaller if you quickly unclick all of the wheels. The basket has a clever cover so you can conceal the items inside it, but the cover can also be rolled out of the way so the stroller can be fully packed with a baby changing bag or other useful things. If you’re planning to take lots of long walks and perhaps even run with the stroller, there are few models that can measure up to the Thule Urban Glide 2 Double when it comes to functions and how nice the stroller is to push.

8. Baby Jogger City Mini GT Double

Very spacious sibling stroller with full lying position, long hoods and compact folding

Max. weight lying/sitting: 9/22.5 kg Width: 76 cm Type of seat unit: Normal Includes rain cover/apron: No/no Adapter for baby car seat: Yes Wheels: Puncture-free foam-filled wheels Handle: Knee-joint Converts to single stroller: No Reversible seat units: No

Baby Jogger City Mini GT Double

The Baby Jogger City Mini GT Double is a side-by-side sibling stroller with fixed, forward-facing seat units. The stroller has four relatively large, foam-filled wheels and because the front wheels swivel (but can be locked), this is a sibling stroller that can easily move through both an urban environment and more uneven terrain or even snow. If you want to use the sibling stroller with a newborn baby, you can buy a carrycot but unfortunately no adapter for a baby car seat. The City Mini GT Double has a high maximum weight and the seat units are also very spacious, both widthways and lengthways. This gives the stroller a very long period of use. The backrest on the Baby Jogger City Mini GT Double can be folded down to a flat lying position so it’s comfortable for the child to sleep in. The stroller has no adjustable footrest, but you can buy a simple footrest separately.

The hoods give very good shade from the sun when fully extended, and have two peepholes in clear plastic, which means you can see the children even when the hoods have been extended. The stroller’s knee-joint handle can be set to several different angles, so it’s comfortable to push regardless of how tall or short you are. You don’t get the best lift from the handle, but it works OK and the stroller rolls very well and feels easy to steer. The basket is spacious and easy to access, above all from the sides which are made from elasticated mesh. The stroller has a convenient handbrake on the right-hand side of the chassis, with a clear catch that must be released before you can undo the brake.

The Baby Jogger City Mini GT Double is 76 cm wide, which is sufficiently narrow for you to be able to move easily both on public transport and inside shops. The major advantage of the GT Double compared with other spacious sibling strollers is how compact it is when you fold it. By lifting the stroller straight up with the two folding straps in the centre of the seat units, the Baby Jogger City Mini GT Double folds up in the middle and the chassis locks itself. This makes the stroller very easy to store at home or when it’s not in use, but it’s also compact enough to go into most cars and can even work as a larger travel stroller. The Baby Jogger City Mini GT Double's main disadvantage is that the seat units can’t be reversed to face backwards, but otherwise it only has strengths. There are very few other manufacturers who can combine good value with a spacious and compact sibling stroller like Baby Jogger manage to do.

9. UPPAbaby Vista

Convenient and spacious sibling stroller with a large basket, can easily be transformed into a single stroller

**Max. weight lying/sitting: ** 9/15 or 22.7 kg **Width: ** 65 cm **Type of seat unit: ** Ergonomic **Includes rain cover/apron: ** Yes/no **Adapter for baby car seat: ** Yes **Wheels: ** Puncture-free PU wheels Handle: Telescopic **Converts to single stroller: ** Yes Reversible seat units: Yes, separate

UppaBaby Vista (Duo)

When it comes to strollers, preferences in different parts of the world often vary significantly. But American brand UPPAbaby have succeeded in breaking through these barriers. **UPPAbaby Vista ** is essentially a single stroller with a carrycot and seat unit but it can be expanded to work for one additional child using two sets of adapters. Two so you can attach the carrycot to the chassis at the front, and the others to raise the seat unit. If you want to have the seat unit at the front and the chassis above, you need to buy an extra sibling “rumble seat” to attach at the front of the pushchair. If there’s an age difference between the children that means you only need the sibling stroller for the early period, the Vista is a very good value solution. The two sets of adapters cost about £25 each.

The UPPAbaby Vista is also well designed for siblings who are a little older. The European maximum weight for the main seat is 15 kg, but in the USA it’s approved up to 22.7 kg. The UPPAbaby Vista is amongst the best vertical sibling strollers at offering a lot of space between the seat units. With the height adapters on and both seat units facing backwards, the front child has plenty of space between them and the other seat unit. The seat units can be inclined to resting and lying position, still without either becoming cramped. And yet the stroller is a compact one, and once folded up it's about the same size as a normal single stroller. For a sibling stroller, it’s narrow, but still broad enough for the stroller to feel stable. The Vista can handle slightly more uneven surfaces, but rolls best on a flat surface in an urban environment.

The handle can be set to a couple of different positions, and the UPPAbaby has a really clever standing board that you can buy separately, making the Vista capable of transporting three children at once. Unlike many other vertical sibling strollers, the basket size doesn’t suffer from there being a sibling seat. The gigantic basket on the Vista can hold a full 13 kg, and works extremely well for doing the food shop. Since 2017, the Vista has puncture-free PU wheels and the hoods have long sun visors that provide UV protection. The UPPAbaby Vista is a very clever solution for anyone who needs to change often between a single and sibling stroller, and it's easy to understand why many families quickly find it essential.

Phil & Teds Dash

Phil & Ted’s Dash three wheeler can be used both as a single and sibling stroller in several different constellations. The Dash can be used with a separate carrycot for a newborn. When it's time for the child to sit up but you don’t yet feel ready for the child to face forwards, you can buy a sibling seat. You can attach this in three different ways: facing backwards on top of the chassis when the stroller is being used with one child, facing forwards on top of the chassis with a baby in a soft carrycot underneath, and facing forwards lower on the chassis with an older sibling sitting in the main seat unit in front. The main seat is very generous in terms of space, with a maximum weight of a full 25 kg, and a normal-sized seven year old can travel comfortably in it. However, the backrest only offers a resting position. The full lying position that you open up with a zip is dished for a soft carrycot and doesn’t work for an older child to sleep in. The hood on the P&T Dash is long and provides plenty of cover. On the Dash, unlike older P&T strollers, the back section is also solid. If you want to open it up you can and there's a layer of mesh fabric to provide ventilation.

As a sibling stroller, it's the convenience of the Dash that’s its main strength. The stroller is only 64 cm wide but can cope with a total child weight of 35 kg and still feel really easy to push. You can easily manoeuvre it with one hand. The large, puncture-free wheels are high quality, and the stroller’s suspension means it can also cope with gravel and slightly uneven terrain. The hand brake on the P&T Dash is both clear and easy to use, and the knee-joint handle is comfortable to hold. It takes a few attempts to learn how to fold the Dash, but the stroller can be folded in a single piece even with the sibling seat on, and is only marginally larger than a normal single stroller. The basket is gigantic, but with two larger children in the stroller a lot of the storage space disappears as a footrest for the rear seat.

The main disadvantage of the Dash as a sibling stroller is that both seat units are forward-facing. With a baby in a soft carrycot and a larger sibling above it works well, and the same is true of two slightly larger children. It’s the transition period when the baby doesn’t want to lie down but perhaps still needs to be facing backwards that’s tricky with the Dash. We also feel that with the sibling seat on the bottom the sitting position is on slightly too much of an angle, and we’d have liked to see a hood being included for the seat. A common criticism of lengthways sibling strollers is that the lower seat is too low, but neither the children who travelled in the stroller nor our parent testers complained about this. There’s even plenty of visibility to the sides for the child sitting underneath. The P&T Dash is an easy to push, narrow, convenient and versatile sibling stroller that works really well for anyone prioritising accessibility in all environments.

11. Emmaljunga NXT Twin

Sturdy sibling stroller that can cope with rough terrain and has both normal and ergonomic seat units

Emmaljunga NXT Twin Flat

Emmaljunga expand their NXT series with an uncompromising NXT Twin, for which you can choose between ergonomic and normal (Flat) seat units. Or why not one of each? Both seat units and carrycots also work on Emmaljunga's NXT90 and NXT60 single chassis, which means you can create a convenient package solution for a growing family.

But we should talk about the size of the NXT Twin first. The stroller is 79 cm wide at the widest point, and that’s a lot. If you often travel with your children on public transport, a sibling stroller of a maximum 75 cm is recommended. And the NXT Twin is long too. With the handle in normal position, and a seat unit and a carrycot on the chassis, it’s a full 130 cm long.

The Emmaljunga NXT Twin has many strengths. You can buy it with both puncture-free and pneumatic wheels. The swivel front wheels can be locked in a fixed position. If you choose pneumatic wheels, the phenomenal suspension makes the stroller really nice to push. The NXT Twin works well on gravel paths, grass and in snow. At the same time, it’s very easy to steer the NXT Twin and you can easily turn it, making it easy to manoeuvre in an urban environment.

The Emmaljunga NXT Twin has a cosy carrycot. The hood has a built-in carrying handle, and the carrycot can be released from the chassis with just one hand. Regardless of whether you choose the ergonomic or normal seat unit, it has sitting, reclined and lying positions. The seat units can be reversed, have adjustable footrests and swing-away safety bars. In lying position, the seat units feel the same size, as the Flat seat unit has an edge at the hood end that folds up when you recline the back. In sitting position, the Flat seat unit feels a bit more spacious, above all lengthways.

The adjustable knee-joint handle can be folded in towards the stroller, making the NXT Twin shorter for travelling on the bus. The sibling stroller is also surprisingly compact when folded. You remove the seat unit and carrycot first, after which you fold the attachments for these. The two on the sides are pushed into the middle, while the central attachment folds forwards. And finally, you fold the handle downwards and forwards. The chassis alone doesn’t take up much space vertically when folded. If you then pack the seat units on top, the NXT Twin will fit in many estate or larger cars.

The Emmaljunga NXT Twin is a sibling stroller that can easily be adapted to taste or need. Being able to attach both ergonomic and normal seat units to a chassis is a unique and popular function. You can also choose between a wide range of upholsteries and different wheels. The price is high, but this seems to be a new standard for reversible side-by-side sibling strollers. If you can afford it, it's the size of the NXT Twin that will be the biggest disadvantage of this stroller.

All about Siblings strollers

A sibling stroller is a buggy that holds at least two children at the same time. All strollers in this test has been designed to work both for a baby and a larger child, and for two slightly larger children at the same time. A sibling stroller can either have the seat units side-by-side or in a tandem configuration, where one seat unit is placed in front of and/or above the other. Some sibling strollers require a separate carrycot for you to be able to use the stroller with an infant. In others, you can combine the seat unit with a soft carrycot. Before buying a sibling stroller, you should decide whether you want the children facing you even when they’re sitting up, as many sibling strollers have seat units that are only forward-facing.

How important is the width of a sibling stroller?

You should also be conscious of the width of the sibling stroller. You need to make sure you can get around in your everyday life as normal without getting stuck in lifts, door openings or the stroller being too big to go into your car boot. If you live in a big city, what’s known in Sweden as the Stockholm dimension can be useful. This means that a stroller can be a maximum of 75 cm wide to work without problems on public transport, which includes lifts on underground systems, door openings on buses and trains, barriers and other narrow spaces. In most cases, strollers of up to 80 cm wide also fit, but there are still some exceptions. So if you live in a big city, it’s a good idea to choose a stroller that sticks to this limit.

How nice is it to push the stroller?

There are several aspects you should take into account when you choose a sibling stroller. With two children in the stroller, of course it’s heavier to push, so the actual buggy itself shouldn’t weigh too much. This makes things easier if you’re taking a walk on rougher terrain or in snow, where you have to push harder anyway. Often the more expensive strollers are lighter, but there are also good cheap sibling strollers that have a reasonable weight.

If you’re going to travel in the car with the stroller often, you may prefer to buy a sibling stroller that can be folded in one piece with all the parts on rather than one that you have to partially dismantle. You should also make sure that the handle can be height adjusted so it works for everyone who’s going to be pushing the stroller on a regular basis, and that the seat units are big enough to hold even the older child for a while into the future. If you plan to do a lot of countryside walks, it’s a good idea to have larger, pneumatic – air-filled – or foam wheels, while if you’re going to spend your time shopping in the city a narrower stroller that’s easier to steer is a better choice.
