ABSTRACT:
An adjustable bed is provided within a substantially rectangular bed frame and a headboard secured to the bed frame. The plurality of adjustable caster assemblies are provided for affixing to a respective side rail of the bed frame, and the caster assemblies cooperate to allow both elevation of the bed frame and thus the mattress supported on the bed frame, and inclination of the bed frame and mattress. Accordingly, the elevation of the head of the bed can be raised or lowered with respect to the foot of the bed, and similarly the elevation of the foot of the bed can be easily adjusted with respect to the head of the bed. Each of the caster assemblies includes adjustment members secured to a side rail of the bed frame, and first and second legs pivotably connected to the adjustment member and pivotably connected to each other adjacent the roller.
