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.
