ABSTRACT:
A mattress spring structure (10) is provided with a strengthened central area (C) thereon to provide greater support for a user's body lumbar region when received thereon. The support is provided with a strengthening structure (30) having a continuous frame member (54) and a strengthening pattern (53). The continuous frame (54) encircles coil springs (12) over a major expanse of the mattress's central area (C); this frame is connected to mattress coils along the frames longitudinal (34, 36) and traverse (38, 40) segments. The strengthening pattern (53) has two metal bars (51, 52) arranged inside and connected to the continuous frame member (54). The strengthening pattern (53) may be connected to the spring coils (12) and contain additional metal straps (56, 59). The strengthening structure (30) is positioned and arranged to causes substantially uniform depression of adjacent coil springs to the continuous frame member (54) in the lumbar zone thereby eliminating any undesired upward pressure into the user's back.
