Abstract
Stepped-edge and side-support members, systems, assemblies, and related methods for an innerspring assembly or other core are disclosed. In one embodiment, an innerspring assembly or core is provided having an interior area of a first height surrounded by one or more exterior, perimeter area(s) of shorter height(s) to provide a stepped-edge innerspring assembly or core. At least a portion of side-support members are placed onto at least a portion of the top surface of the perimeter area to provide edge-support for the innerspring assembly or core. In this manner, a greater portion of the side-support members can be disposed in the sleeping area of the innerspring assembly or core since the underlying perimeter area provides spring support to the side-support members. Further, this support can assist in retention and/or recovery of the shape of the side-support members to further prevent or reduce compression set of the side-support members.
