Abstract
A hydraulically or pneumatically operated relaxation chair has a floor engaging base, a padded seat-thigh rest member pivotally secured to the top of the base, and a padded back and head rest assembly pivotally secured to the top of the base at the rear of the seat-thigh rest. A calf rest is pivotally secured to the front of the seat-thigh rest. Padded arm rests are pivotally secured to each side of the back rest member. Controls in the arm rest control the operation of fluid rams to selectively move and position the seat-thigh rest, the calf rest, the back and head rest, and each arm rest relative to one another and to the base independently or as units. The arm rest members may have separate upper and forearm members pivotally connected and powered by fluid rams whereby the members pivot relative to one another and to the back and head rest assembly independently or as a unit. In one embodiment, the seat-thigh rest and calf rest members are a pair of laterally spaced left and right seat-thigh and calf support members pivotally connected and powered by rams whereby the calf and seat-thigh support members pivot relative to one another and as units relative to the base. The head rest may be separate from the back rest to pivot relative thereto, and the back rest may have an expandable lumbar support.
