Abstract: A support surface includes a plurality of interconnected node groups, where each node group includes at least two nodes connected by a fluid passage. The plurality of interconnected node groups define a node array. A source of pressurized fluid, such as pressurized air is connected with the node array.

Abstract: A support surface includes a plurality of air cylinders disposed crosswise and aligned to define the support surface. The air cylinders include a first foam therein. Adjacent cylinders are provided with varying support characteristics to define multiple support zones along a length of the support surface. At least some of the plurality of air cylinders additionally include an integrated bolster at ends thereof that is formed of a second foam, firmer than the first foam.

Abstract: A support surface suitable for use with a stretcher includes multiple foam pads of independent zonal pressure support such that a transfer of force by pressure on one foam pad to an adjacent foam pad is limited.

Abstract: A support surface includes a foam base layer including a foam bottom layer and a pair of foam side edges disposed adjacent sides of the foam bottom layer. The foam side edges are firmer than the foam bottom layer. A honeycomb material layer is disposed over the foam base layer, and a cover surrounds the foam base layer and the honeycomb material layer. The combination of foam and honeycomb material provides an effective support surface resulting in superior pressure relieving characteristics, resistance to bottoming out, good edge support, and reduced manufacturing costs.

Abstract: A mattress includes features that improve support and comfort. The mattress may include one or more of a head section positioned to support a user's head, a torso section coupled with the head section via a first multi-plane bond, and a foot section coupled with the torso section via a second multi-plane bond. The foot section may be retractable, and the torso section may include a cross-linked foam part and a seat ledge. The seat ledge is positioned to define a catch point for the user upon articulation of the mattress.
