Size

In general double pushchairs are larger than single models, especially when they're side by side buggies, like the Kolcraft Geo 3 and UPPAbaby Vista 2. The good news is that this extra width lets them to accommodate heavier children without straining the chassis. They also have other key features that help them stand out, like generously-sized pop-out canopies with SPF 50 and windows that peek out and swivel lock front wheels that help navigate tight spots like shopping aisles cups with a single parent holder, a smart fold mechanism that is able to be completed by one hand; and 10 inch back wheels that aren't made for rough terrain but can handle city streets and theme parks quite well.
In terms of cost, these types of lightweight buggies that are side-by-side are quite affordable.
Weight
The heavier a double buggy is the more easy it will be 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 plenty of features including the large pop-out canopy, SPF50 and a peekaboo window, a quick-release folding system that can be stowed flat in seconds and a four-wheel suspension for rough terrain and a swivel wheels on the front, which allows you to maneuver tight shops and supermarket aisles.

Buggies that are narrow can be used to squeeze through small spaces. Side-by-side models let you to keep the track of your children and ensure their safety while you go to the park or shopping. They also come with a wide range of seat configurations that allow you to modify the seat as your children grow, and some even offer the option of adding a ride-on or car seat.
The Joie Evalite duo is an excellent example. It can be used to hold two seats or a car-seat. The adaptors allow you to convert from a single seat to a double in just seconds. lightweight twin buggy comes with a huge pop-out canopy sunshade that has UPF 50+ protection, adjustable legrests, and a peekaboo window in both seats. A standing fold is easy to make and quick.
Tri-fold buggies, such as the iCandy Peach are another versatile option. Their slim frames are ideal for narrow doors and aisles, and they can comfortably accommodate twins or a baby and a big kid thanks to the addition of UPPAbaby's "PiggyBack' board (which you can purchase separately). They provide a spacious basket, and come with all the extras you might require, including rain covers and liners.
Tandem buggies are usually made with your kids sitting side-by-side. This can make them easier and more stable to push on uneven surfaces, but they can be a challenge to maneuver up and over kerbs. They have a larger footprint than a single-seater and may be too long to fit through doors.
