INTERNAL MATTRESS WALL STRUCTURES INTERLOCKINGLY ENGAGEABLE WITH MATTRESS INNERSPRING ASSEMBLIES

摘要

Internal mattress wall structures interlocking engageable with mattress innerspring assemblies (12) provide a structurally integrated resilient mattress support edge to which padding upholstery (43) is integrally attached. The wall structures include a main body section with a vertically oriented wall surface and a plurality of parallel flanges (29) which mechanically engage the innerspring assembly by compression fit between the intermediate and terminal convolutions of the perimetrical coils of the innerspring assembly. Corner structures contiguous with side and end wall structures form a contiguous smooth side wall support characteristics comparable to an innerspring assembly.
