High and low profile mattress foundation frames

A low profile mattress foundation frame for supporting a plurality of composite material spring modules, the foundation frame comprising:

• two parallel longitudinal perimeter members and a parallel central longitudinal member between the longitudinal perimeter members, major widths of the longitudinal perimeter and central members in substantially the same plane,
• transverse end perimeter and intermediate members attached to and extending orthogonally over and attached to the longitudinal perimeter and central members, a major width of the transverse end perimeter and intermediate members parallel to the plane of the major widths of the longitudinal perimeter and central members,
• a facia board extending between ends of the longitudinal perimeter members, a major width of the facia board perpendicular to the major widths of the longitudinal perimeter and transverse members, and a narrow bottom edge of the facia board flush with bottom surfaces of the longitudinal members, and
• upper longitudinal members attached to the transverse end perimeter and intermediate members and adapted to support a plurality of composite material spring modules.

A high profile mattress foundation comprising:

• a plurality of composite material spring modules;
• and
• a foundation frame comprising:
• two parallel longitudinal perimeter members and a parallel central longitudinal frame member between the longitudinal perimeter members,
• a plurality of transverse members attached to and extending over and perpendicularly from one longitudinal perimeter frame member to the other, a major width of each of the transverse frame members orthogonal to a major width of the perimeter and central longitudinal frame members, and a top edge of the transverse frame members parallel to the major width of the perimeter and central longitudinal frame members, and
• upper members attached perpendicularly to top edges of the transverse members and parallel to the perimeter and central longitudinal members, the upper members being supported by the top edges of the transverse members to support the plurality of composite material spring modules and,
• a facia board extending between ends of the longitudinal perimeter members, a major width of the facia board perpendicular to the major widths of the perimeter and central longitudinal members and parallel to the major widths of the transverse members, and a bottom edge of the facia board substantially flush with bottom surfaces of the longitudinal members.
