ABSTRACT:
Pads and mattresses having novel aggregate fillers are described. Aggregates containing a highly viscous gel-like fluid and a mixture of re-expanded polystyrene beads and silica beads are utilized to produce lightweight pads and mattresses which provide support with favorable pressure distribution, thereby minimizing high pressure contact areas between a user and the pad or mattress. The novel pads and mattresses particularly are useful for the minimization of pressure sores, which may result in situations wherein a user must remain on a pad or mattress for long periods of time.
