The adjustable bed has two chains (12a, 12b) with rigid links (13) mounted on a rigid base (3a, 3b). Levers (4a, 4b, 5a, 5b) allow the head and back portion or leg and foot portion to be raised and lowered. Transverse rods (11) act as pivots between the links of the chain and slats (14) forming the surface of the bed are attached to mountings on the rods. |
