Abstract

A portable back support comprises a base plate and a cushion layer attached to the base plate. The cushion layer has an upper portion and a lower portion, the lower portion having a pair of laterally spaced extremities. The base plate has an arcuate shape in transverse section thereby enabling the extremities to provide lateral support. The lower portion further includes an inflatable bladder enabling the contour of the cushion to be varied. The bladder is movably connected to the base plate. The rear surface of the bladder is supported by the base plate. The vertical position of the bladder can be adjusted by a suitable device such as two straps connected to the bladder.
