ABSTRACT:
A removable support accessory (30) is positionable relative to one or more support bars (15, 16) of a bed frame (12) of a collapsible bed (10) to provide a substantially greater support base and more planar bed and seat support planes (23, 82). The support accessory (30) thereby reduces discomfort that would otherwise be imposed by ridges, buckets, and rolling caused by sagging cables (20, 22) and the narrow support bars (15, 16). The support accessory (30) includes a longitudinal unit (34) having substantially rigid sections (38, 40) and nonrigid sections or hinges (46) that permit support accessory (30) to be compactly folded for storage. The support accessory (30) also includes a substantially rigid central unit (36) that extends the length of the nonrigid section (46) to provide continuous support along the length of the longitudinal unit (34). Velcro strips (58, 60, 68, and 70) are employed to secure the central unit (36) to the longitudinal unit (34 ), and the longitudinal unit (34) to the bed frame (12). The support accessory (30) can be employed when the collapsible bed (10) is extended in a bed-forming position (21) or collapsed in a sofa-forming position (80).
