ABSTRACT:
A three piece sofa bed recliner has an end frame, seat frame and back frame. The frame ends are linked overlapped. Interengaging the seat frame with the back frame enables a simple conversion process from sofa bed to recliner. The back frame and end frames fold toward each other as the interlocked seat frame is moved backward. The end frame and back frame interlock with the end frame leg and the seat frame and back frame interlock releases during conversion. Reconversion is a simple forward pull unfolding the respective frames on their legs with an extending pivoted leg set between the end frame and back frame. Wheels facilitate movements. The end frame may be used to be a chaise lounge.
