The Bugaboo Bee is a compact infant-to-toddler travel system with a full set of flexible features for life on the fly, including a height-adjustable handlebar; a seat that reverses, reclines and extends; the ability to accommodate various car seats; and a one piece integrated design that almost folds on its own. A prestressed spring collapses the seat 2-dimensionally and at the same time the legs of the Bugaboo Bee embrace the seat 3-dimensionally and in this motion the stroller transforms into 88x43x31 compact centimeters.
