Buying a Tandem Double Buggy
If you have twins or children similar in age, a tandem double buggie is a great option. They are narrower than side-by-side buggies and are great for narrow spaces like doorways, public transport and terrain that is rocky.
Some convert into travel systems that take 2 carrycots or car seats. They are often heavier, longer and less stable than a single pushchair.
Convertible
Whether you're looking for a convertible stroller that converts from single to double or to add a second seat to an existing one, there's several options available. The Vista V2 from UPPAbaby is a large, gorgeous stroller that can easily be converted from a single to a double by adding the rumble seat (available separately). However, it's expensive and less maneuverable than other dual strollers since the second seat is located to the left of the front seat. The Nuna Demi Grow is a comparable model with a wide range of seating options, but lacks under-seat storage when used in doubles mode.
double pram pushchair include twin buggies with all-terrain wheels and joggers with fixed wheels that can hold two kids. These are more expensive, however, they are designed for long-distance trips over rough terrain and come with more expensive resales.
Independent recline of the seat
If you require a double buggy that is able to transport children of various ages, you'll want one that has recline that is independent for both seats. This allows your child of a higher age to rest in the back while the baby sleeps in the bassinet and vice versa.
Take into consideration the width of your stroller to determine the ease of you to get through doors and public transportation. If your doorways are very narrow, you might want to consider a side by side pushchair such as the Mountain Buggy Duet. It has a footprint that is similar to a single stroller but can still accommodate two seats and car seat adaptors.

Tandem buggies are generally longer than side by side models, making them more difficult to maneuver around and down kerbs. However, they can accommodate more combinations of car seats/car seats/seats and can make a great option for twins and siblings of various ages. They also tend to be more expensive than single-to-double buggies but are worth the investment if you intend to keep it for a long time and will retain a decent amount of resale value should you decide to sell it off after your children have grown out of it.
Another important feature to look for is if the seat backs are able to recline independently of each other as this will let you put your child in the best position for napping or observation. This is particularly important if you have a young child in the rear seat, who will be inclined to lie down and take a snooze while the older child wants to sit up and observe their surroundings.
Certain brands come with a unique design for their seats that allows the back seat to fully recline into a nearly flat position which is perfect for babies. For instance the iCandy Orange has raised stadium-style seating and can recline both the included toddler seat and the add-on RumbleSeat to multiple positions, so your kids can have a choice of where they will sit, as well as offering an excellent UPF 50+ canopy with windows that can be seen from afar.
Wider than twin buggies
They are ideal for siblings of different ages, and you can move around without worrying about your children touching. They're usually a bit larger too with one seat placed behind the other and offering a fully-flat recline for newborns (or a more upright position for toddlers).
A popular option is the Mountain Buggy Duet, which is the tiniest side-by-side model available and features the same footprint as one buggy. It also has an adjustable handle, making it easy for parents of different heights to push as well as an adjustable handbrake, which is useful when tackling difficult terrains. It is suitable from birth and is compatible with a range of car seats and carrycots. This means it makes an excellent travel system.
Another alternative is the iCandy Wave, which has a simple one-click to fold and is able to be used in mono or duo mode. The clever frame expands in width to accommodate an additional chair and can be used to accommodate up to two car seats or carrycots. This makes it a great option for older siblings who want to be seated together. It's a little longer than other models, but it's light to steer and comes with soft suspension that can handle kerbs.
There are a lot of 3-wheeler inline tandems that are available Check out Phil and Teds inline models, or iCandy's Peach and Pear buggies, for instance that offer stability and swift steering. They are often folded into one buggy if you are limited in space at home or need to transport it from your car to the bus station.
Be aware that a double wide buggy will be more heavy and more bulkier than one compact buggy. Be sure you know what you want before you buy. You'll need to take it on and off subways, trains and buses regularly so it needs to be easy to use and manage. You may also have to juggle it on and off the car seat when you take your children to school or nursery so you'll need to be aware it can be easily manoeuvred in tight spaces.
From your birth, you are a suitable candidate
Whether you're expecting twins or have another child after your first, you're going need to find a stroller that can accommodate the entire family. Double buggies tend to be heavier and bulkier, as well as more expensive than single strollers. However, they are more maneuverable in narrower doors, or around obstacles like curbs. They are also compatible with piggyback ride-along boards (either from the manufacturer or via an accessory purchase) so you can transport three children at the same time.
double pram pushchair in the front of the other, so they're usually a better option for families with two children who are close enough in age to be able to live well together. They're not completely safe. Siblings seated side-by-side may punch or kick each other, and children of different heights could argue over who sits taller. A tandem high-low model is able to solve this issue by elevating the seat towards the rear, which prevents your child's height from being on the bottom and not getting much of a view.
The iCandy Wave is a good alternative for parents looking for an adjustable double buggy that can be converted into a carrycot that can accommodate both the newborn and the older child. It features a clever frame that expands widthways when you add a second seat, and folds flat for compact storage. The seats are cushioned and comfortable, the straps are simple to fasten, and the buckles are among the best we've seen on any of our tests. The canopies are large in size and UPF 50+ protection, as well as a peekaboo window. Both seats can recline independently.
The only drawback to the iCandy tandem is that it's a bit costly. But a high-quality tandem will last you for years and retain the highest resale value, so at the end of the day you'll probably recoup some of the cost. It doesn't have the same range of seating options as others of our top picks however, the iCandy is a great choice for families who don't wish to spend a lot.
