Buying a Tandem Double Buggy
If you have twins or children similar in age, a tandem double buggie is a great choice. They're a bit smaller than side-byside buggies, and ideal for maneuvering tight spaces such as entrances, on public transportation and on rocky terrain.
Some can be converted to travel systems that can take two carrycots or car seats for children. They are typically 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 a double. The UPPAbaby V2 is a spacious, gorgeous stroller. It is easily changed from a single to a dual by adding a seating area with a rumble. It is more expensive and less maneuverable due to the fact that the second seat is positioned behind the first seat. The Nuna Demi Grow is a similar option with great seating flexibility, however it isn't equipped with storage under the seat when used in doubles mode.
Other alternatives include twin buggies with all-terrain wheels as well as joggers that have fixed wheels that can hold two kids. read what he said are more expensive, however, they are designed for long-distance trips over rough terrain, and come with higher resale prices.
Independent seat recline
If you require a double buggy that is able to carry children of different ages then you're going to need a buggy that has an recline independent for both seats. This will allow your older child to rest while the baby is in a bassinet, and vice versa.
It is also important to consider the width of the stroller as it will impact the ease of navigate through doors and on public transport. If you have extremely narrow doors, it may 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 however, it is able to take 2 seats and car seat adaptors.
Tandem buggies generally are smaller than side-byside models, and aren't as difficult to maneuver around kerbs however, they can accommodate a wider variety of car/car/seat combinations, making them a good option for twins or siblings of different age. They can also be more expensive than single-to-double buggies but are a worthwhile investment if you intend to keep it for a long time and have a good amount of resale value if you decide to sell it off when your children have grown out of it.
Another important feature to look for is if the seat backs are able to recline independently from one another since this will allow you to put your child in the best position to nap or observe. This is crucial for children who are in the back seat and wishes to rest while the child in the front prefers to sit up to observe the surrounding.
Certain brands have a unique design that allows the back seat of their vehicles to recline into a position that is nearly flat, which is ideal for infants. The iCandy Orange, for example is a stadium-style seat that can be reclined into multiple positions. It also has UPF 50+ canopy and peekaboo windows.
Wider than twin buggies
It's not necessary to have twins to benefit from a bigger double buggy. They're great for siblings of different ages and allow you to get around without having to worry about your children touching. They're usually a bit longer with one seat positioned behind the other. double buggy for twins can be reclined completely for infants, or put in an upright position for toddlers.
Mountain Buggy Duet is a popular choice. It has the slimmest design side-by-side on the market, and a footprint that is like one stroller. It features an adjustable handle that makes it easier for parents to push and a handbrake, which can be useful on hills that are steep. It is suitable from birth and is compatible with a range of car seats and carrycots. This means it's a great travel system.
Another option is the iCandy Wave, which has a simple one-click to fold and is able to be used in mono or duo mode. The frame's clever design can be expanded to accommodate an additional chair and can be used up to two car seats or carrycots. This makes it a great option for older siblings who wish to be seated together. It's a little longer than other models, but it still feels light and has a comfortable suspension for the 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 they provide stability and swift steering. Most of them can be folded into the size of one buggie which is useful when you have trouble storing it at home or need to transport it into and out of the boot on public transportation.
It's important to remember that a wide double buggy will feel heavier and bulkier than a single buggy that is smaller So make sure it's what you need before purchasing. You'll have to get it on and off subways, buses, and trains often, so it should be simple to use and manage. You may need to juggle the car seat on and off when you take your child to school or nursery.

The best time to start is when you are born.
If you're expecting twins, or you have a child following your first, you're likely to require an appropriate pushchair for the entire family. Double buggies are typically a bit heavier, bulkier and cost more than single strollers, however they are also easier to manoeuvre in narrower entrances or around obstacles like curbs. Many double buggies are compatible with piggyback boards (available from the manufacturer or as an add-on). This lets you transport three children simultaneously.
Tandem pushchairs put one child ahead of the other. They are a good option if your children are close in age and are able to get along. But they're not completely safe Side-by-side chairs could kick or punch one another, and children on different heights can squabble over who should sit higher. This problem can be solved by a tandem high-low model that elevates the seat in the back. Your older child will not be seated on the lower part of the car, and won't get much of an eye.
The iCandy Wave is a good option for parents who are looking for a convertible double buggy that includes a carrycot that is able to accommodate both infants and an older child. It has an innovative frame that 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 easy 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 canopy is spacious and large with UPF 50+ protection as well as peekaboo windows.
The only downside to the iCandy tandem is that it is a bit costly. But a high-quality tandem will last for a long time and will have the highest resale value, which means that in the end, you'll likely recoup some of the cost. It also doesn't offer the same variety of seating configurations as others of our top choices, but the iCandy is a great choice for families who don't want to shell out a lot of money.
