摘要： Mattresses and methods for processing a flexible foam material for use in a mattress to provide a mattress foam material that has more consistent firmness over time and area. The methods include pre-conditioning the foam pad or mattress by applying a force across a substantial portion of a major surface of the mattress to compress or stretch the height of the foam, the length of the foam, and/or the width of the foam to break or open closed cells. In certain embodiments, the force is applied by repeatedly pressing a platen against the foam pad or placing the foam pad between one or more rollers.

摘要： Systems and methods include a spring-coil assembly having non-linear load-deflection characteristics that are substantially similar to foam. In particular, the systems and methods described herein include a first set of encased springs that are in a partially compressed state and a second set of shorter springs. These two sets of springs may be arranged in alternating rows such that the resulting spring-coil assembly displays non-linear load-deflection characteristics similar to foam.
