What to Look For in a Double Travel Buggy
A side-by-side double that has a compact footprint (for narrow entrances and on public transport). Add carrycots or seats (with adaptors), to increase the frame's weight capacity for children up to 50 pounds.
Budget double with back and front suspension for uneven surfaces. Large storage basket, padded handlebars, and large storage basket.
Size
Double pushchairs are typically more spacious than single ones, especially when they are side-by-side buggies like the Kolcraft Geo 3 or UPPAbaby. The good news is that this extra width allows them to handle heavier children without straining the chassis. They also come with other key features that make them stand out, like large pop-out canopy sizes with SPF 50 and peekaboo windows as well as swivel lock front tires that help navigate tight spots such as shopping aisles; cup holders for one parent and a smart fold mechanism that can be done one-handed; and 10-inch back wheels that aren't built for tough terrain but are able to handle city streets and theme parks fairly well.
In terms of cost these kinds of lightweight buggies that are side-by-side are quite affordable.
Weight
The heavier the double buggy the more easy it is to move and lift. The Joie Evalite Duo, which is the most lightweight of our Lab tests, is a great choice if weight is an issue. It's got many features, including a large pop-out canopy with SPF50 and peekaboo window and a quick-release folding system that can be folded flat in a matter of seconds and a four-wheel suspension for rough terrain and a swivel wheels at the front that makes it easy to navigate narrow aisles in supermarkets and shops. It's also affordable at just over a thousand dollars. It can also carry twins or a baby and toddler with the purchase of an additional'sidepack'.
Flexibility
A double buggy is a great option for parents with twins or even a toddler and baby. Narrow tandem buggies are great for fitting through tight spaces, while side-by-side models keep your children accounted for and help you to keep your eyes on them as you travel around the supermarket or park. A lot of buggies come with a variety seats so that you can alter the seat as your child grows. Some allow you to add a car seat or ride-on board.
The Joie Evalite duo is a great example. It can hold two seats or a car seat and its adaptors that are easy to use allow you to change from a single seat to a double in a matter of seconds. It also has a nice-sized pop-out UPF 50+ canopy sunshade with adjustable leg rests as well as windows that peek out from both seats as well as a standing fold that's quick and easy to do with just one hand; and a top-quality suspension that can take care of rough terrain.
The iCandy Peach tri-fold buggy is another alternative. double umbrella stroller are perfect for narrow aisles and doors and they can comfortably accommodate twins, a baby or a big kid thanks to the addition of UPPAbaby's "PiggyBack board (which you can purchase separately). The basket is generous and includes all the accessories, such as raincovers and liner.
Tandem buggies typically have children seated together, which can make them easier to push and more stable on uneven surfaces however they can be difficult to maneuver between kerbs. They have a bigger footprint than a single seater and can be too big to fit through doors.

Comfort
One of the most comfortable lightweight doubles we've tested This buggy comes with seats that are elevated to the level of stadium seats so that your children can enjoy the view; large UPF 50+ canopy with peekaboo windows; padded toddler seat and add-on RumbleSeat, which has an adjustable leg and foot rests; as well as the cup holder that is single-parent. Testers are awestruck by the way that the seats recline by pushing the levers under each seat, and say that the straps are simple to secure and remove with just one hand. It's also simple to fold, thanks to a twist mechanism on the handle that makes it as simple as possible, and stores with the backrest up to make it easy to access.
This is the perfect choice for families who want to develop with their children. It is available in 30 different configurations. It can hold twins with a toddler as well as three children with the 'PiggyBack board'. The large basket and soft suspension make it suitable for kerbs, as in the city. It's also reasonably priced.
