Abstract: A furniture seating support system includes furniture support structure and a frame having tubular elements connected to the support structure. First and second tubular elements are positioned parallel to each other. A tubular cross member is connected to the frame between the first and second elements. A pair of pivoting joints each connect first element ends to the support structure, permitting first element rotation. Elastically flexible support straps with elastomeric elements are connected to the first and second elements to support an occupant. The cross member position is adjustable to vary strap stiffness. A furniture member cavity is accessible by raising the first element.

Abstract: A furniture member joining system includes a U-shaped fastener having first and second posts extending transversely from a post body.

At least one fluid inlet valve and at least one fluid discharge valve are distributed about the inflatable mattress. A plurality of attachment devices connected to the inflatable mattress are used to temporarily or permanently attach the inflatable mattress to the furniture member. The inflatable mattress is collapsible for storage within a furniture member interior envelope.
