Wire spring assemblies made of nestably stackable half units

摘要

Wire spring assemblies for use in furniture items such as mattresses and seat cushions are made of two half units. The half units include spring elements extending from a generally planar deck with the spring elements containing complementary connecting structures at their distal ends which enable the half units to be assembled together by inverting one half unit relative to the other, aligning the two half units and snap-fitting the connecting structures of the spring elements together to form a double sided mattress or seat core. The assemblies are then upholstered in a normal fashion.
