Buying a Tandem Double Buggy
If you have twins or children close in age, a tandem double buggy is a great choice. They're narrower than side-by-side buggies, and ideal for maneuvering narrow spaces like doorways, on public transport and on rough terrain.
Some convert into travel systems that use two carrycots or car seats. They are typically heavier, longer and less stable than a single pushchair.
Convertible
Whether you're looking for a convertible stroller that can be converted from a single to a double or to add an additional seat to an existing one, there's many options to choose from. The Vista V2 from UPPAbaby is a big, beautiful stroller that converts easily from a single model to double by incorporating the rumble seat (available separately). It is more expensive and less maneuverable because the second seat is located in front of the first seat. The Nuna Demi Grow is a comparable model with a wide range of seating options, but does not have storage under the seat when used in doubles mode.
Other alternatives include all-terrain twin buggies and fixed-wheel joggers that can hold two children. They are generally more expensive but they're designed for long-distance trips over rough terrain and can have greater resales value.
Independent seat recline
If you need a double buggy that can carry children of different ages then you're going to want one that has recline that is independent for both seats. This will allow your child's older to rest in the back while the baby is in the bassinet and vice versa.
Take into consideration the size of your pushchair to determine how easy it is for you to navigate through doors and on public transportation. If you have narrow doors, it could be worth considering a side-by-side pushchair, such as the Mountain Buggy Duet which has the advantage of having a footprint that is similar to a single buggy, however, it is able to use two seats and car seat adaptors.
Tandem buggies tend to be larger than side-by-side models, and therefore are more difficult to maneuver up and down kerbs. However they can be able to accommodate more combinations of car seats, carrycots and seats and are an excellent choice for twins and siblings of different age. They also tend to be more expensive than single-to double buggies, but are a worthwhile investment if you intend to keep it for many years and will retain a decent amount of resale value if you decide to sell it when your children have grown out of it.
double buggy sale allows you to put your child in a comfortable position for naps or to observe. This is important if your child is in the back seat and wishes to rest while the child in the front prefers to sit up and observe the surrounding.
A few brands have a unique design for their seats that allows the back seat to fully recline to an almost flat position that is perfect for babies. For example, the iCandy Orange has raised stadium-style seating that can recline both the toddler seat that comes with it and the add-on RumbleSeat into multiple positions so that your children have a the option of deciding where to sit, as well as offering an excellent UPF 50+ canopy that has windows that can be seen from afar.

Larger than twin buggies
They are ideal for siblings with different age groups, and they allow you to move about without having to worry about your children touching. They're typically a larger with one seat in front of the other. The seats can be reclined fully for newborns or in an upright position for toddlers.
Mountain Buggy Duet is a popular choice. It is the tiniest design side-by-side on the market, and a footprint comparable to a single stroller. It has an adjustable handle that makes it easier for parents to push, and a handbrake, which is useful on steep hills. It is suitable to use from birth and can be used with a variety of car seats and carrycots.
The iCandy Wave is another option. It can be folded in mono or duo mode with just one click. The frame's clever design can be expanded to accommodate a second chair and can be used up to two car seats or carrycots. This makes it a great choice for older siblings that wish to sit together. It's a little longer than other models, yet it's easy to steer and has soft suspension that is able to handle kerbs.
There are plenty of 3-wheeler tandems with inline wheels that offer stability and swift steering. Take a look at Phil and Teds inline models, or iCandy Peach and Pear buggies. These can often be folded into a single buggy if you have limited space at home or you need to carry it from the car to the bus.
Be aware that a two-wheeled buggy is heavier and more bulkier than a single compact buggy. Be sure you know what you want prior to making a buy. It is likely to be used on buses, trains, and subways frequently therefore it must be simple to use and manage. You might need to manage the car seat on and off when you take your child to school or the nursery.
From birth, you are a suitable candidate
If you're expecting twins or have a second child after your first, you're going to need to find a pushchair that fits the entire family. Double buggies are generally larger, heavier and cost more than single strollers, but they are also easier to maneuver in narrower entrances or around obstacles like curbs. Many are also compatible with piggyback ride-along boards (either from the manufacturer or as an accessory purchase) which means you can carry three children at the same time.
Tandem pushchairs put one child in front of the other. They're a good choice if your children are of similar ages and get along well. They're not foolproof. Siblings who are sitting side-by-side could punch or kick one another and children with different heights can fight over who is sitting higher. A tandem high-low model can solve this problem by elevating the seat at the rear, which prevents your child's height from being sat on the bottom and not getting any view.
The iCandy Wave is a good option for parents who are looking for an adjustable double buggy that can be converted into a carrycot that is able to accommodate both infants and an older child. It has an intelligent frame that can be expanded in size when you add the second child seat. It can also fold flat to make it a compact storage. The seats are cushioned and comfortable, the straps are simple to fasten and the buckles some of the best we've seen on any of our tests. You can recline both seats independently and the canopies are spacious and large with UPF 50+ protection and peekaboo windows.
The only drawback to the iCandy tandem is that it is quite expensive. But a high-quality tandem will last for many years and have a high resale price, so at the end of the day you'll likely recover a portion of the cost. The iCandy doesn't have the same seating arrangements as our other top selections. However, it's an excellent choice for families who don't want to spend a lot of money.
