Buying a Tandem Double Buggy
If you have twins or children very similar in age, a tandem double buggie is a great choice. They're a bit smaller than side-byside buggies and ideal for navigating tight spaces such as entrances, on public transportation and on rocky terrain.
Many also transform into travel systems that take 2 carrycots or car seats. However, they can be heavier and longer than single pushchairs and may feel less stable bumping up kerbs.
Convertible
If you're looking for convertible stroller that converts from single to double or to add a second seat to an existing one, there are a variety of options available. The Vista V2 from UPPAbaby is big, beautiful stroller that converts easily from a single to a double by adding the rumble seating (available separately). It's costly and less maneuverable than other dual strollers because the 2nd seat goes behind the front seat. Nuna Demi Grow provides a similar choice but lacks storage underneath the seat when it's used as a double stroller.
Other options include all-terrain twin buggies and fixed-wheel joggers which can be used to accommodate two children. They tend to be more expensive but they're designed for long-distance trips over rough terrain and could have a higher resale value.
Reclining seat recline independently

If you're looking for a double buggy that is able to transport children of various ages, you'll require a model with an recline that is independent for both seats. This will allow your older child to relax in the back while the baby sleeps in the bassinet, and the reverse.
Consider the size of your pushchair to determine how easy it is for you to get through doors and public transportation. If you have narrow doorways then it might be worthwhile to consider a side-by-side pushchair like the Mountain Buggy Duet which has the advantage of having a footprint comparable to a single buggy but can still take 2 seats and car seat adaptors.
Tandem buggies are generally smaller than side-byside models and so aren't as easy to manoeuvre up and down kerbs, however they can be able to accommodate a wider range of car/car/seat combinations, and are a great option for twins or siblings of different ages. They can also be more expensive than single-to-double buggies but are worth the investment if you plan to keep it for a long time and will have a decent amount of resale value if you decide to sell it after your children have grown out of it.
double stroller with car seat to look for is whether the seat backs are able to recline independently of one another since this will allow you to place your child in the best position to nap or observe. This is essential if your child is in the back seat and would like to rest while the child in the front prefers to sit up to observe the surroundings.
Certain brands have a distinctive design that allows the back seat of their vehicles to recline to a position that is almost flat, ideal for infants. The iCandy Orange, for example, has stadium-style seating that can be reclined to various positions. It also offers UPF 50+ canopy and peekaboo windows.
Wider than twin buggies
There's no need to have twins to benefit from a bigger double buggy - they're ideal for siblings of different age groups and let you get around without worrying about your children touching each other. They're typically a bit larger with one seat placed behind the other, and typically offering a fully-flat recline for babies (or a more upright position for toddlers).
Mountain Buggy Duet is a popular option. It is the slimmest design that is side-by-side and a footprint that is similar to the footprint of a single stroller. It also comes with an adjustable handle, making it easy for parents of different heights to push, and an adjustable handbrake, which can be useful when you have to climb difficult hills. It is suitable for use from birth, and can be paired with a range of car seats and carrycots.
The iCandy Wave is another option. It can be folded in either mono or duo mode with just a single click. Its innovative frame can be expanded to allow for a second seat and it can be used with two carrycots or car seats so it's an excellent choice for older siblings who wish to sit together and enjoy the view. It's a little longer than other models, but it's light to steer and comes with soft suspension to tackle the kerbs.
There are a variety 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. Often these can be folded into the size of a single buggy which is useful if you struggle with storage at home or frequently need to transport it into and out of the car when you travel on public transport.
Be double stroller with car seat that a double wide buggy is more heavy and heavier than a single compact buggy. Be sure to know what you want prior to making a purchase. You'll be taking it on and off subways, trains and buses frequently, so it must be simple to use and manage. It is possible that you will need to move the car seat when you take your child to school or the nursery.
From birth, you are a suitable candidate
Whether you're expecting twins or have a second child after your first, you're likely to need to find a stroller that can accommodate the whole family. Double buggies are generally a bit heavier, bulkier and cost more than single strollers, but they are also easier to manoeuvre in narrower entrances or around obstacles like curbs. Many double buggies work with piggyback boards (available from the manufacturer or as an accessory). This allows you to transport three children simultaneously.
Tandem pushchairs put one child in front the other. They are a good choice if your children are of similar ages and are good friends. But they're not foolproof Side-by-side chairs could kick or punch one another, and children on different heights can squabble over who gets to sit higher. A tandem high-low model is able to solve this problem by elevating the seat to the rear, preventing your child's older one from being sat on the bottom and not getting much of a view.
The iCandy Wave is a great option for parents looking for an easy-to-use convertible double buggy that can fit both a newborn in a carrycot and an older child in the main seat. It features a smart frame that can be expanded in width when you add a second seat. It folds flat for compact storage. The padded seats are comfortable, the straps easy to secure and the buckles some of the most comfortable we've seen on any of our tests. The canopy is 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 is quite expensive. But a high-quality tandem will last for years and retain a high resale price, so in the end you'll likely recover some of the cost. It doesn't have the same variety of seating configurations that the other top choices, but the iCandy is a great choice for families that don't want to spend a lot.
