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.

Cette invention concerne un matelas composite conçu pour constituer à plat une surface de repos et pour pouvoir être replié sur lui-même en vue de son rangement à l'intérieur d'un sofa-lit. L'objet de l'invention comprend un garnissage composite entre un panneau de revêtement supérieur et un panneau de revêtement inférieur. Une série linéaire de pattes sont cousues aux rives supérieures du panneau de revêtement supérieur et fixées, de préférence à agrafes, à intervalles prédéterminés aux rives inférieures du garnissage composite ou à la face inférieure de celui-ci. Les panneaux inférieur et/ou supérieur du garnissage composite comportent une série de lignes d'affaiblissement pour faciliter le pliage du matelas tout en maintenant en place tous ses éléments constitutifs pour réduire, au pliage, le tassement et les déplacements desdits éléments les uns par rapport aux autres.
