A side-by-side that slides narrow to fit through doorways, then widens for two — plus mono, duo, and twin modes on one chassis.
The Donkey solves the classic side-by-side problem: it's the rare twin-capable stroller that still fits through a standard doorway. A clever slider lets you expand from a single (mono) to a single-plus-shopping (duo) to a full twin, and it narrows back down so you're not stuck at every threshold. Two bassinets side by side make it one of the better true-twin-from-birth options, the ride is plush, and it's built like a tank. What you pay for all that is, well, a lot — this is the most expensive frame here by a wide margin, accessories are premium-priced, and it's heavy and hefty to lift into a trunk. Skip it if your budget is anywhere near tight or you rarely need the twin width; the value math only works if you'll genuinely use the side-by-side twin mode and can stomach the price.
