Buying a Tandem Double Buggy
A tandem double buggy could be a great choice for twins or children who are very 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 to travel systems that use two carrycots or child car seats. However, they are heavier and longer than single pushchairs, and might feel less stable when bumping up kerbs.
Convertible

If you're looking for a convertible stroller that can be converted from a single to a double or to add another seat to an existing one, there's a variety of options available. The Vista V2 from UPPAbaby is a spacious, gorgeous stroller that can easily be converted from a single stroller to double by adding the rumble seat (available separately). It is more expensive and less maneuverable due to the fact that the second seat is placed in front of the first seat. Nuna Demi Grow is a similar model however, it doesn't have storage underneath the seat when 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 are generally more expensive but they're designed for long trips over rough terrain and can have a higher resale value.
Independent seat recline
If you need a double buggy that is able to transport children of various age groups, then you'll need a buggy that has an recline that is independent for both seats. This will allow your older child to sit back and relax while the baby sleeps in the bassinet and vice versa.
Take into consideration the width of your pushchair, as this will determine the ease of you to maneuver through doors and public transport. If your doorways are very narrow, you might be considering a side-by-side pushchair, such as the Mountain Buggy Duet. It has a footprint similar to a single stroller, but can still fit two seats and car seat adaptors.
Tandem buggies are usually smaller than side-byside models and therefore aren't difficult to maneuver around kerbs however, they can accommodate a wider variety of seat/carrycot/car seat combinations making them a good option for twins or siblings of various age. They are also more expensive than single-to double buggies, but are a worthwhile purchase if you plan to keep it for years and have a good amount of resale value should you decide to sell it after your children have grown out of it.
double buggy sale allows you to put your child in the most comfortable position for naps or observation. This is essential when your child is in the back seat and wishes to take a nap while the more mature child prefers to sit up and observe the surrounding.
A few brands have an exclusive seat design that allows the back seat to fully recline into an almost flat position that is perfect for infants. The iCandy Orange, for example is a stadium-style seat that can be reclined to various positions. It also offers UPF 50+ canopy and windows that peek out.
Larger than twin buggies
They are perfect for siblings of different ages, and you can move around without worrying about your children touching. They are usually a little bit longer, with one seat behind the other. The seats can be reclined completely for babies or placed in an upright position for toddlers.
A popular choice is the Mountain Buggy Duet, which features the slimmest side-by-side design available and features a footprint similar to one buggy. It also features an adjustable handle, which makes it easier for parents of different heights to push and an adjustable handbrake, which can be useful when you have to climb difficult terrains. It is suitable for use right from birth, and can be used with a range of car seats and carrycots.
The iCandy Wave is another option. It folds in mono or duo mode with just one click. The clever frame can be expanded to accommodate the second chair and can be used up to two car seats or carrycots. This makes it an ideal choice for older siblings that wish to sit together. It's slightly larger than other models, but it still feels light and has a comfortable suspension for curbs.
There are also plenty of 3-wheeler tandems inline available - check out Phil and Teds inline models or iCandy's Peach and Pear buggies, for instance they provide stability and swift steering. They are often folded down to the size of one buggy, which is helpful for those who struggle with storage at home or have to lug it in and out of the boot when using public transport.
It's important to keep in mind that a large double buggy will feel heavier and bulkier than a compact single buggy Make sure that it's what you need before purchasing. You'll have to get it off and on subways, trains and buses regularly so it needs to be easy to operate and manage. You might need to manage the car seat when you take your child to school or nursery.
Suitable from birth
Whether you're expecting twins or have a second child after your first, you're likely to require a stroller that can accommodate the entire family. Double buggies are typically heavier, bulkier, and more expensive than single strollers. However they are much easier to maneuver in tighter doorways or around obstacles such as curbs. They are also compatible with piggyback ride-along boards (either from the manufacturer or via a separate accessory purchase) which means you can carry three children at a time.
Tandem pushchairs place one child ahead of the other. They're a good choice if your children are close in age and are able to get along. However, they're not 100% secure: Siblings in side-by-side seats could kick or punch each other, and children who are different heights can argue over who sits higher. This issue can be addressed by a tandem high-low model that elevates the seat at the back. Your older child will not be seated on the bottom of the car and won't be able to get an opportunity to see.
The iCandy Wave is a great choice for parents looking for an easy-to-use double buggy that converts to fit both a newborn in a carrycot, and an older child in the main seat. It features a clever frame which expands in width when you add a second child seat. It folds flat to make it a compact storage. The cushioned straps, buckles, and seats are all of the highest quality we have encountered in our testing. You can recline both seats independently and the canopy is large and generous with UPF 50+ protection as well as windows that peek out.
The only drawback of the iCandy is that it's on the expensive side however, a good tandem will last for years and retain its resale value, so you'll probably get back some of the cost in the end. It doesn't come with the same selection of seating options as the other top picks however the iCandy is a great choice for families that don't want to shell out a lot of money.
