Abstract
A cushioning support device and a method for making the same are disclosed. The device comprises a first polyurethane foam having a non-slip sheet attached on a surface of the first foam, a second polyurethane foam having a resting sheet attached on a surface of the second foam, and a compound pressure-redistributing body. The first and second polyurethane foams are arranged one over another into a stack which is welded and envelops to form at least an internal pocket along a weld line. The internal pocket houses the pressure-redistributing body, and it comprises a foam and a solid gel attached on a top surface of the foam, wherein the solid gel is securely positioned by way of melting. Dips of the gel can lodge into the small interstices of the foam material during the melting process; the gel gets into a solid state after solidification.
