Abstract: A system for leveling and securing a partition, including a base or shoe for receiving the partition, and a channel or slot formed in the base by at least a first sidewall, an opposing second sidewall, and a lower wall positioned at least in part between the first and second sidewalls. The system further includes a rocker assembly and a clamp assembly positioned within the slot. The rocker assembly includes a stationary component positioned adjacent the first sidewall and a pivoting component pivotably connected to the stationary component on a side of the stationary component opposite the first sidewall. The clamp assembly may include a stationary block adjacent the second sidewall, a first sliding block slidably connected to the stationary block and adjustable by a first fastener, and a second sliding block slidably connected to the stationary block and adjustable by a second fastener.

Abstract: A sealable, composite cushion is disclosed having a plurality of resilient support member horizontally disposed to one another and surrounded by a fluid impervious membrane. Each resilient support member has a known Indentation Force Deflection (IFD) value and is located in the cushion based upon medical criteria to provide zones of varying support. In an embodiment, the resilient members are bonded to the membrane and act as tension members to maintain the cushion's form while under a load. As a result, the cushion resists further deflection not only by the resilient members' resistance to compression, but also by an increased internal pressure. Accordingly, the cushion of the present invention is a composite of fluid flotation and compression resistance. A valve may be incorporated into the cushion to regulate the fluid floatation characteristics of the cushion or to assist in its transportation.
