ABSTRACT:
A mattress is provided with an innerspring unit, one or more layers of foam material disposed over the innerspring unit, and a mattress cover enclosing the innerspring unit and foam layers. The innerspring unit has first and second border wires spaced apart from each other by a predetermined distance and a plurality of spring coils arranged in a plurality of rows between the border wires. Each of the coils is formed of a helical wire member having a plurality of spaced apart convolutions. A plurality of compressible support members are provided between adjacent rows of coils. The support members are generally in the shape of an I-beam, with an upper portion of a first width, a middle portion of a second width, and a lower portion of a third width. The upper portion of each support member is provided between a first two adjacent convolutions of the coil springs and the lower portion of each support member is provided between a second two adjacent convolutions of the coils. The compressible support members increase the effective stiffness of the coils, thus providing the mattress with increased firmness. In another embodiment, the support members may be provided with a positioning stub for anchoring them between adjacent rows of spring coils.
