Abstract
A mattress includes a spring extending between first and second points to provide a first spring rate in a first direction. A polymer fiber structure is provided between the first and second points and adjoins the spring. The polymer fiber structure includes fibers interlinked with one another to provide the second spring rate in the first direction. An example method of manufacturing a mattress is provided that includes arranging springs to provide a mattress innerspring. A polymer fiber structure is introduced in a first state to the innerspring to provide an assembly. The assembly is further processed and the polymer fiber structure is simultaneously altered from the first state to a second state.
Claims13
A mattress comprising:
- a spring core assembly including a plurality of coil springs, the spring core assembly having a length, a width, and a height, wherein the coil springs provide a first spring rate in a direction of a height of the spring core assembly;
- and
- a polymer structure having a height substantially corresponding to the height of the spring core assembly, a length substantially corresponding to one of the length and width of the spring core assembly, and a thickness of about 0.5-4.0 inches, the polymer structure comprising polyester fibers interlinked with one another, wherein the polymer structure is arranged outside of outermost ones of the plurality of coil springs, wherein the polymer structure provides a second spring rate in the direction of the height of the spring core assembly, wherein the second spring rate is an increased spring rate in the direction of the height of the spring core assembly relative to a polymer structure comprising only randomly oriented fibers, and wherein the polymer structure has an ILD of about 45-110 pounds and a density of about 1.2-3.0 pounds per cubic foot.
A mattress comprising:
- a spring core assembly including a plurality of coil springs, the spring core assembly having a length, width, and a height, wherein the coil springs provide a first spring rate in a direction of a height of the spring core assembly;
- and
- a polymer structure having a height corresponding to the height of the spring core assembly, a length substantially corresponding to one of the length and width of the spring core assembly, the polymer structure comprising polyester fibers interlinked with one another, wherein the polymer structure is arranged outside of outermost ones of the plurality of coil springs, wherein the polymer structure provides a second spring rate in the direction of the height of the spring core assembly, wherein the second spring rate is an increased spring rate in the direction of the height of the spring core assembly relative to a polymer structure comprising only randomly oriented fibers.
