The Bugaboo Donkey Stroller Base 2015 is the convertible stroller that grows and flows with your family. Whether you have one kid, two kids or twins, one stroller fits all! In just three simple clicks, this stroller system converts from the full-size mono mode to the full-size duo mode (with the Bugaboo Donkey Duo Extension Kit, sold separately), as well as multiple seat positions. With flexible luggage options, the Bugaboo Donkey Base offers plenty of room for all your essentials, too. It also features more handlebar positions and a new Comfort Harness. This harness comes with five independently adjustable, easy-to-reach straps to make room for growing hips, waists or shoulders. These straps also just click into one central buckle, and with just one click, all the straps click out of the central console. The Bugaboo Donkey Stroller Base 2015 comes with the chassis, one stroller seat, base seat and bassinet fabric, carry handle, air pump, underseat storage, rain cover and removable extra luggage basket.
