South Bay International is the Inventor and Patent holder of the edge support technology, the Wedge. While this technology has been licensed for use by others, and there are imitators, it is a proprietary feature of the Sleep Science line. This technology supports and stabilizes the complete sleeping surface. The Wedge prevents sagging and extends the life of the mattress by providing support and stability when sitting on the edge of the bed. The mattress supports the weight of the body in a way that memory foam mattresses without the Wedge do not.
The science behind the Wedge:
• The Wedge is constructed of premium quality, high density HR polyurethane foam.
• It provides needed support to the outer edge sitting surface of the mattress.
• The Wedge extends the effective sleep surface of the memory foam mattress by 20%, effectively allowing for an edge to edge sleeping surface.
• The Wedge adds longevity and durability by supporting and reinforcing the overall structural integrity of the mattress.
