Buying a Tandem Double Buggy
A tandem double buggy can be a great option if you have twins, or children who are close in age. They're smaller than side-by-side buggies, and ideal for maneuvering tight spaces, such as entrances, on public transportation and on rough terrain.
Some can be converted into travel systems that take two carrycots or car seats for children. However, they are heavier and longer than single pushchairs and might feel less stable when bumping up the kerbs.
Convertible
If you're looking for a convertible single-to-double stroller or want to add an additional 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 stroller to a double by incorporating the rumble seat (available separately). However, it's pricey and less maneuverable than other dual strollers since the second seat goes in front of the front seat. The Nuna Demi Grow is a similar model with a wide range of seating options, but does not have storage under the seat when used in doubles mode.
Other options include all-terrain twin buggies, as well as fixed-wheel joggers that can accommodate two children. They are more expensive, however, they are designed for long trips on rough terrain, and come with a higher resale price.
Independent seat recline
If you require a double buggy to carry children of different ages then you're going to require a model with an recline independent for both seats. This allows your child of a higher age to be able to relax while your baby is in a bassinet and vice versa.

You'll also have to think about the size of the pushchair as it will impact how easy it is to navigate through doors and on public transport. If your doorways are very narrow, you may be considering a side by side pushchair like the Mountain Buggy Duet. It has a footprint that is similar to a single stroller but it can accommodate two seats and car seat adaptors.
Tandem buggies generally are slightly longer than side-by-side models and therefore aren't easily maneuverable through kerbs and up and down, but they can accommodate a bigger range of car seat/car seat combinations, and are a great option for twins or siblings of different age. double buggy sale 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 sell it on after your children have grown out of it.
Another thing to look out for is if the seat backs are able to recline independently from one another because this allows you to place your child in the best position for napping or observation. This is especially important if you have a young child in the rear seat, who will prefer to lay back and relax while the more mature child wants to sit up and observe their surroundings.
Certain brands have a distinctive design that allows the back of their vehicles to recline fully into a position that's nearly flat, which is ideal for infants. For instance the iCandy Orange has raised stadium-style seating that can recline both the toddler seat that comes with it as well as the optional RumbleSeat into multiple positions to give your kids a the option of deciding where to sit, as well as providing an excellent UPF 50+ canopy with windows that can be seen from afar.
Wider than twin buggies
You don't need to have twins to benefit from a wider double buggy - they're ideal for siblings of different age groups and let you go about your day without worrying about your children touching. They're typically a bit larger, with one seat sitting behind the other, and typically with a fully-flat recline option for babies (or a more upright position for toddlers).
A popular choice is the Mountain Buggy Duet, which has the slimmest side-byside design on the market and has a footprint similar to one buggy. It comes with an adjustable handle that makes it easier for parents to push, and a handbrake, which is helpful on steep hills. It can be used from birth and is compatible with a range of car seats and carrycots. This means it is a great travel system.
The iCandy Wave is another option. It can be folded in mono or duo mode with just a single click. The clever frame expands to accommodate a second chair and can be used to accommodate up to two car seats or carrycots. This makes it a fantastic option for older siblings who wish to sit together. It's a bit longer than other models, but it's easy to steer and has soft suspension that is able to handle kerbs.
There are also a variety of 3-wheeler tandems inline available Check out Phil and Teds inline models or iCandy's Peach and Pear buggies for instance - which provide stability and swift steering. Most of them can be folded down to size a single buggy, which is helpful when you have trouble storing it at home or frequently need to transport it into and out of the car on public transportation.
Be aware that a double wide buggy will be heavier and heavier than one compact buggy. Make sure you know what you want prior to making a buy. You'll have to get it off and on trains, buses and subways frequently, so it must be easy to use and manage. You might need to manage the car seat when taking your child to school or the nursery.
From your birth, you are an ideal candidate
There will be a need for a pushchair for your entire family, whether you're expecting twins, or you have another child after having your first. Double buggies are generally heavier and bulkier as well as more expensive than single strollers. However they are much more maneuverable in narrower doorways, or around obstacles like curbs. Many are also compatible with piggyback ride-along boards (either from the manufacturer or as an additional accessory purchase) which means you can carry three children at once.
Tandem pushchairs put one child in front the other. They are a good choice if your children are close in age and are good friends. But they're not foolproof: Siblings in side-by-side seats can kick or punch each other, and children on different heights can squabble over who sits higher. This issue can be resolved by a tandem high-low model that raises the seat at the rear. Your child's older one will not be sitting at the lower part of the car, and won't be able to get a look out.
The iCandy Wave is a great choice for parents looking for an easy-to-use convertible double buggy that can fit a newborn into a carrycot and an older child in the main seat. It has a clever frame which expands in width when you add a second child seat. It can also fold flat to make it a compact storage. The cushioned seats are comfortable, the straps are simple to fasten and the buckles some of the most comfortable we've seen on any of our tests. Both seats can recline independently, and the canopies are spacious and large with UPF 50+ protection and windows that can be seen from a distance.
The only drawback to the iCandy tandem is that it's a bit expensive. However, a quality tandem will last you for a long time and will have a high resale price, which means that in the end, you'll likely recoup some of the cost. double buggy converts to single doesn't have the same selection of seating options as the other top choices however, the iCandy is a good option for families who don't want to shell out a lot of money.
