A pet bed (10) that is foldable to a compact configuration when not in use. When it is desired to use the pet bed (10), the pet bed is folded to an extended configuration in which a sleeping surface (14) is extended horizontally and a frame (12) spaces the sleeping surface from the floor. The frame (12) for the pet bed (10) includes one or more stops (40) to prevent collapsing of the frame when the pet bed is in the extended configuration. The stops (40) release as the pet bed is folded back into the storage configuration.
