Abstract
Abstract High and low profile mattress foundation frames have perimeter and transverse members, and upper members to which spring modules are attached to support a grid over the frame, to form a flexible support surface for a mattress. In a high profile version of the frame, transverse members are oriented with a major width perpendicular to a major width of the perimeter members, to provide structural rigidity and increased height to the frame. Low profile spring modules, such as the described composite material spring modules, supported by the high profile frame form a foundation which is comparable in overall height to conventional mattress foundations which use wire-form spring modules. In a low profile version of the frame, the major widths of the perimeter and transverse members are arranged parallel, and longitudinal members are supported by the transverse members. Spring modules, such as the described composite material spring modules with integrally formed attachment fittings, are attached to the longitudinal members. The low profile foundation can be used with mattresses of larger-than-average thickness, without excessively increasing the overall height of the bedding ensemble. The high and low profile foundations include relatively small facia boards oriented with a major width vertical, to economically provide a continuous exterior surface to the frame perimeter as an upholstery frame.
