A modular tandem with dozens of seat arrangements — face-to-face, both forward, one reclined — that flexes as your kids' needs change.
The City Select 2 is the shape-shifter of double strollers. With two seats it offers a huge number of configurations: kids facing each other, both facing out, one napping flat while the other watches the world. It starts as a single and expands to a double (and even a third bench/board), and the upright stacked design keeps it narrow enough for normal doorways and store aisles, which side-by-sides can't promise. It's a fantastic pick for growing families who want to rearrange seats as siblings' ages and moods change. The honest downsides: it's genuinely heavy, the seats and adapters add up in cost, and folding it with both seats on is a two-step, take-up-the-trunk affair. Skip it if you mostly do quick solo outings and want something you can toss in the car one-handed — this rewards families who value flexibility over featherweight convenience.
