A bed moveable from a lowered position to a raised position includes two pairs of guides. In each pair, one guide is oriented so as to be substantially vertical and the other guide is disposed at an angle to the first guide. A lift assembly is located in each guide. A support including a frame is coupled to the lift assemblies. A drive system moves the lift assemblies in two directions, thereby lowering and raising the support. As the support is raised, it moves from a substantially horizontal orientation to a non-horizontal orientation.
