Adjustable configuration seating

Abstract

The adjustable configuration seating has a pair of opposed lateral rigid frame members with a continuous web or sling type seat and back panel extending therebetween. The seat and back panel is secured in place between the two frame members by a series of crossmembers extending between the frame members, with a single adjustably positionable tension crossmember also extending between the frame members to hold the seat and back panel taut. Conversion between relatively upright and reclining configurations is accomplished by repositioning the tension crossmember between the frames, and turning the assembly ninety degrees to position the selected seating surface to face generally upwardly. The seating surface for the other configuration is a separate side or surface of the seating web or sling. The seat may be folded by hinging the crossmembers together and folding the web or sling between the two frame members as they are drawn together.
