Abstract: A bed assembly is provided particularly for geriatric use. The bed includes a mattress supported by a frame having a plurality of supporting legs, and bolsters are provided on either side of the mattress, mounted so that a top surface of each is substantially even with the top of the mattress. An undercarriage support structure including a pair of horizontal channel members are provided for receiving the legs of the mattress supporting frame and preventing substantial movement thereof with respect to the bolsters. The horizontal channel members include a pair of end portions which are received by passageways associated with the bolsters and allow the bolsters to be slid up and down off of and onto the undercarriage. A rail is mounted on each bolster for movement from a position below the top of the mattress to a position above the top of the mattress wherein it performs a roll-off preventing function.

Abstract: A tray assembly is provided particularly for utilization with a nursing home bed or the like. The tray includes a substantially flat support surface that gently slopes downwardly from the head portion to the foot portion of the tray, with a vertical lip upstanding from the support surface around the entire tray circumference. A pair of U-shaped rods are provided for mounting the tray on supporting rails of varying spacings, clips of flexible material being mounted on cross portions of the U-shaped rods to attach to appropriate rail sections. The bed toe board mounts rail sections that also can receive the tray so that the tray covers the toe board when not in use.
