Buying a Tandem Double Buggy
A tandem double buggy could be a great choice if you have twins, or children who are close in age. They are narrower than side by side buggies, and are perfect for narrow spaces like doors, public transport and rocky terrain.
Some transform into travel systems that include two carrycots or car seats. However, they are heavier and longer than single pushchairs and may feel less stable as they bump up the kerbs.
Convertible
There are many options for adding a second seating or making a single stroller double. The UPPAbaby is a large, beautiful stroller. It can easily be transformed from a single stroller to a dual by adding a Rumble seat. It is more expensive and less maneuverable due to the fact that the second seat is positioned on top of the first seat. Nuna Demi Grow provides a similar choice however, it doesn't have storage underneath the seat when it's used as a double stroller.
Other options include twin buggies that have all-terrain wheels as well as joggers that have fixed wheels that can be used to carry two children. They are more expensive, but they are designed for long trips on rough terrain and have higher resale prices.
Reclining seat recline independently

If you require a double buggy that is able to transport children of different ages then you're going to need a buggy that has an recline independent for both seats. This will allow your child's older to rest in the back while the baby is in the bassinet, and reverse.
You'll also need to think about the size of the pushchair as this will affect the ease of traverse doors and public transportation. If your doorways are very narrow, you might think about a side-by-side pushchair like the Mountain Buggy Duet. It has a footprint that is similar to a single stroller but can still fit two seats and car seat adaptors.
Tandem buggies are typically longer than side by side models, which makes them more difficult to maneuver around and down kerbs. However, they can accommodate more combinations of car seats/car seats/seats and are an excellent choice for twins and siblings of different age groups. They can also be more expensive than single-to double buggies, but are worth the purchase if you plan to keep it for many years and will have a decent amount of resale value if you decide to sell it when your children are out of it.
This feature will allow you to put your child in the most comfortable position for naps and observation. This is particularly important if you have a child younger than in the rear seat who may want to lie back and take a snooze while the older child would prefer to sit up and observe their surroundings.
Some brands have a unique design that allows the back of their vehicles to fully recline into a position that's almost flat, perfect for babies. For instance, the iCandy Orange has raised stadium-style seating that can recline both the toddler seat included and the add-on RumbleSeat into multiple positions so that your children have a the option of where they want to sit, and also comes with an excellent UPF 50+ canopy with windows that peek out.
Wider than twin buggies
There's no need to have twins in order to benefit from a larger double buggy. They're perfect for siblings of various ages and allow you to move around without having to worry about your children touching each other. They're usually a larger with one seat positioned behind the other. The seats can be reclined completely for infants, or put in an upright position for toddlers.
A popular choice is the Mountain Buggy Duet, which is the tiniest side-by-side model available and has an identical footprint to a single buggy. It also features an adjustable handle, which makes it easier for parents of various heights to push and a handbrake that can be useful when you have to climb difficult terrains. It is suitable for use from birth, and it can be combined with a wide range of car seats and carrycots.
Another option is the iCandy Wave, which has the convenience of a single click to fold and is able to be utilized in a duo or mono mode. The frame's clever design can be expanded to accommodate the second chair and can be used up to two car seats or carrycots. This makes it a fantastic option for older siblings who want to sit together. It's a little longer than other models, but it still isn't heavy and has a soft suspension for 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 as well as iCandy Peach and Pear buggies. They are often folded into the size of one buggie, which is helpful if you struggle with storage at home or frequently need to transport it into and out of the car on public transportation.
Be aware that a two-wheeled buggy will be more heavy and heavier than a single compact buggy. Make sure you know what you want before you buy. You'll be taking it on and off subways, buses, and trains often, so it should be easy to operate and manage. It is possible that you will need to move the car seat in and out while taking your child to school or the nursery.
From your birth, you are a good 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 typically slightly heavier, bulkier and more expensive than single strollers, but they are also easier to manoeuvre in narrower doorways or around obstacles like curbs. They are also compatible with piggyback ride-along boards (either from the manufacturer or through an accessory purchase) so you can transport three children at a time.
Tandem pushchairs place one child ahead of the other. They're a great option for children who are of similar ages and get along well. They're not completely safe. Siblings seated side-by-side may kick or punch each other and children with different heights may fight over who is sitting 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 on the bottom and not having any view.
double stroller with infant car seat is a good choice for parents looking for an adjustable double buggy that can be converted into a carrycot that can accommodate both infants and an older child. It has a clever frame that expands in width when you add a second seat and folds down flat to make it a compact storage. The seats are cushioned and comfortable, the straps easy to secure and the buckles are among the most impressive we've seen in any of our tests. The seats can be reclined independently and the canopies are spacious and large with UPF 50+ protection as well as peekaboo windows.
The only downside of the iCandy is that it's a bit on the expensive side but a high-quality tandem will last a long time and maintain its resale value, so you'll probably get back some of the cost in the long run. It 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 spend a fortune.
