Abstract
A stronger foldable bed having a frame and a foldably soft cover attached thereto. The frame has two pairs of side bars each pivotally connected to a central link, a tilt leg pivotally connected to a free end of each side bar, three pairs of scissoring end or middle bars linking the two pairs of side bars, a pair of middle leg each containing a telescoping leg, a reinforcing bar each pivotally connected to one side bar and a sleeve covering on each tilt leg, and a journey limit formed on each tilt leg. The foldable bed is longitudinal stable, simple and strong, without sacrificing the easiness of operation of folding and expanding.
