20090038072 | Fire resistant corner guard - Corner guards suitable for use with a bedding assembly and providing a degree of fire resistance. The corner guards may contain fire/flame resistant (FR) polymeric reagents, flammable polymeric reagents combined with one or more FR agent or have an FR coating. Additionally, the corner guards may have effective FR properties while substantially maintaining the mechanical properties that allow the corner guard to support and protect the edges of upholstered furniture, such as a foundation or sofa. The corner guards arise, at least in part, from the realization that flare ups occurring during the test about the combustion of an FR foundation, result from high burn temperatures causing the corner guard to melt and the subsequently combustion of the melted polymeric material. | 02-12-2009 |
20090106908 | Asymmetrical combined cylindrical and conical springs - A mattress comprising asymmetrical coil springs with nonlinear spring rates provides comfort to users with different weights. The lower portion of the spring is cylindrical and the upper portion is conical or frustoconical.

20110031665 | SYSTEMS AND METHODS FOR CUSHION SUPPORTS - The mattress assemblies have an array of springs extending from a sheet. Each spring in the array may be manufactured by choosing a position for the spring, cutting a profile of the sheet spring in the sheet, peeling back or bending the profile or tab of the sheet, and shaping the profile to form the sheet spring. The array of springs may be formed from creating a plurality of such springs along rows and columns. In certain embodiments, multiple sheets may be stacked to form the sheet spring array. | 02-10-2011 |
20110041252 | Systems and methods for manufacturing springs with foam characteristics - 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. | 02-24-2011 |
