Buying a Tandem Double Buggy
A tandem double buggy can be a great choice when you have twins or children who are very close in age. They're narrower than side-by-side buggies, and ideal for maneuvering tight spaces such as doorways, on public transport and on rocky terrain.

Some can be converted to travel systems that use two carrycots or child car seats. They can be heavier, longer and less stable than a single pushchair.
Convertible
There are a variety of options for adding a second seat or changing a single stroller into double. The UPPAbaby V2 is spacious, gorgeous stroller. double jogging stroller can easily be converted from a single to a dual by adding an Rumble seat. It is more expensive and less maneuverable due to the fact that the second seat is located in front of the first seat. The Nuna Demi Grow is a similar model with a wide range of seating options, but isn't equipped with storage under the seat when used in doubles mode.
Other options include twin buggies with all-terrain wheels as well as joggers that have fixed wheels that can hold two children. They tend to be more expensive but they're designed to last longer on rough terrain, and may have a higher resale value.
Reclining the seat independently
If you're looking for a double buggy to carry children of different ages, you'll need a buggy that has an recline that is independent for both seats. This will allow your older child to relax while the baby is in the bassinet, and vice versa.
You'll also have to think about the size of the pushchair, as it will impact the ease of navigate through doors and on public transport. If your doors are 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 however can still accommodate two seats and car seat adaptors.
Tandem buggies are generally larger than side-by-side models, making them more difficult to maneuver around and down kerbs. However they can also accommodate a wider range of combinations of seats/carrycots/car seats and can make the perfect choice for twins and siblings of different age groups. They also tend to be more expensive than single-to-double buggies, but are a worthwhile investment if you intend to keep it for years and will have a decent amount of resale value if you sell it on when your children are out of it.
Another important feature to look for is if the seat backs are able to recline independently of one another because this allows you to place your child in the best position to nap or observe. This is important when your child is in the back seat and wishes to take a nap while the more mature child prefers to sit and observe the surrounding.
Certain brands have a distinctive design that allows the back of their vehicles to fully recline into a position that is almost flat, ideal for infants. For instance, the iCandy Orange has raised stadium-style seating and 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 they will sit, as well as providing an excellent UPF 50+ canopy that has windows that peek out.
Wider than twin buggies
It's not necessary to have twins to benefit from a bigger double buggy - they're ideal for siblings of various ages and allow you to get around without worrying about your children touching each other. They are usually a little larger with one seat in front of the other. The seats can be reclined completely for newborns or in an upright position for toddlers.
A popular choice is the Mountain Buggy Duet, which is the tiniest side-by-side model 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 a handbrake, which can be useful when you have to climb difficult hills. It can be used from birth and is compatible with a range of car seats and carrycots, which means it's a great travel system.
Another alternative is the iCandy Wave, which has an easy one-click fold and can be utilized in a duo or mono mode. The frame's clever design can be expanded to accommodate a second chair and can be used with up to two car seats or carrycots. This makes it an ideal choice for older siblings that want to sit together. It's a little longer than other models but still feels light to steer and comes with soft suspension to tackle kerbs.
There are also plenty of 3-wheeler inline tandems available - check out Phil and Teds inline models or iCandy's Peach and Pear buggies, for instance - which offer stability and swift steering. These can often be folded into a single buggy if you are limited in space at home or need to transport it from the car to the bus station.
Be aware that a two-wheeled buggy is heavier and heavier than one that is compact. Make sure you know what you want prior to making a buy. You'll be taking it on and off subways, buses, and trains often, so it should be easy to operate and manage. You may need to juggle the car seat when taking your child to school or to nursery.
From your birth, you are an ideal candidate
You'll need a stroller for your entire family, regardless of whether you're expecting twins or you have a second child after you've had your first. Double buggies tend to be a bit heavier, bulkier and cost more than single strollers, however they are also more maneuverable 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) so you can transport three children at a time.
double push chair place one child in front of the other, and they're usually a better option if you have two kids who are similar in age to function well together. They're not foolproof. Siblings seated side-by-side may punch or kick each other and children with different heights may fight over who is sitting higher. A tandem high-low model can solve this issue by elevating the seat towards 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 choice for parents looking for a convertible double buggy with a carrycot that can accommodate both a newborn and an older child. It has an intelligent frame that increases in size when you add a second child seat. It also folds flat to make it a compact storage. The padded straps, buckles, and seats are all of the best quality we have encountered in our tests. You can recline both seats independently, and the canopies are spacious and large with UPF 50+ protection as well as windows that peek out.
The only drawback of the iCandy is that it's a little on the expensive side but a high-quality tandem will last a long time and maintain its resale value, which means you'll probably get back some of the cost in the end. It doesn't come with the same range of seating configurations that others of our top choices, but the iCandy is a good choice for families who don't wish to shell out a lot of money.
