Abstract: The medical furniture cover includes a plurality of surfaces being formed of a thermoplastic material, the plurality of surfaces including an upper surface and a plurality of side surfaces integral with and extending from the upper surface, the upper and side surfaces being configured to cover corresponding surfaces of a medical furniture. The upper surface is sized to fit the length and the width of the medical furniture, and the cover has an opening opposite the upper surface for fitting the cover over the medical furniture. A periphery of the opening is formed by distal ends of the side surfaces, and an elastic band is attached to the cover and extends along the periphery of the opening for securing the cover to the medical furniture.

Abstract: A bed comprises a bed frame and a bed deck supported by the bed frame. The bed deck comprises a step deck, including a lower deck, an upper deck, a side wall connecting the lower deck to the upper deck, and a recess defined by the lower deck and the side wall. The side wall at least partially surrounds the recess. A mattress comprises a safety mattress extending across the lower bed deck and having air cells including air cells resting on the upper bed deck.

Abstract: An ergonomic passive support surface comprising a set of foam support elements and a pressure equalization layer which is preferably a fibrous fill material layer or foam layer. Pressure distribution is controlled by the characteristics and shape of a foam material. Preferably, the foam material is provided as a set of transverse oriented cylindrical sections, selected for desired support characteristics.

Abstract: A mattress comprises a resilient layer having a lower portion and side walls shaped to generally mate with a recessed bed deck and one or more cells supported in relation to the resilient layer and generally within the recess. The cells have a low air permeability envelope and an inflation structure within the envelope. The inflation structure is configured to expand within the envelope when unloaded to cause the envelope to fill with air.
