Laminated supports for pressure relief

摘要

A laminated support for pressure-relief such as mattresses or cushions comprises at least two layers of foam adhered together, at least one layer consisting of a visco-elastic foam. In embodiments the support may comprise two layers of viscoelastic foam adhered together, one layer having a greater hardness than the other (figures 1 and 2) together with a layer of highly resilient foam (figure 3). These layers are sandwiched between two layers of reticulated filter polyurethane foam.
