    摘要: A composite mattress assembly adapted to be extended flat to provide a sleeping surface and to be folded for storage within a sofa is provided. The composite mattress assembly includes a composite pad assembly surrounded by an upper panel and a lower panel. A plurality of linear flange members are fixedly secured to the top edges of the upper panel and are also secured, preferably by staples, at preselected intervals along the lower edges of the composite pad assembly, or along the bottom surface of the composite pad assembly. A plurality of score lines are located upon one or both of an upper pad member and a lower pad member of the spring assembly, to assist in the folding of the composite mattress assembly, while maintaining fixed relative positions of all components, thereby reducing bunching and relative shifting of mattress materials and components during folding.
