Patent application number | Description | Published |
20090139033 | Channel-cut cushion supports - The support characteristics within a foam mattress body may be varied by inserting reinforcements into channels cut or otherwise formed within the foam. | 06-04-2009 |
20090144907 | Systems and methods for manufacturing fire-retardant mattresses - The systems and methods described herein include, among other things, methods for manufacturing a fire-retardant mattress. In certain embodiments, the methods described herein employ an adhesive tape to secure a sock of fire resistant fabric to the exterior of a mattress core, rendering the mattress fire resistant. The mattress core may be a foam core, an innerspring core, or another type of core. The tape may be a two sided adhesive tape and the fire-retardant (FR) sock may be any suitable fire resistant material. | 06-11-2009 |
20100005595 | Mattress or Mattress Pad With Gel Section - The invention generally relates to a mattress or a mattress pad with one or more gel sections. The gel section may provide improved support and comfort at a localized area of a mattress or a mattress pad. | 01-14-2010 |
20100072676 | PRE-CONDITIONED FOAM PAD - 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. | 03-25-2010 |
20100132123 | TITANIUM MATTRESS MEMBER - A versatile support member constructed of a metallic mesh is provided in a bedding product. The support member is placed on top of the mattress core (whether foam or spring coil) before the mattress cover is attached. The support member may be constructed of titanium wire in a woven or welded mesh grid or web configuration, although other metals (such as, but not limited to, vanadium, chromium, platinum, molybdenum, nickel, iron, zinc), alloys thereof, or fiber composites (such as, but not limited to, carbon or graphite) may be used. The support member may be directly attached to the core or may be secured to the upper or lower border rods by hog rings, stitching, lacing, or other conventional means. | 06-03-2010 |
20100175197 | PERIMETER STIFFENING SYSTEM FOR A FOAM MATTRESS - A stiffening system for the perimeter edges of a foam core mattress comprising a coil spring (or other spring-based) structure disposed along one or more perimeter edges (e.g., one or both side edges, the foot, the head, or a combinations thereof including the foot and both side edges) of a mattress having a foam sleeping area. The perimeter spring structure is rectangular or square in cross-section and provides sufficient stiffness for comfortable seating on the edges of the mattress and is joined to the foam core by planar fabric elements that span the joint between them and are attached to both. The sleep area provides the softness and other salutary effects of a foam sleeping surface while the stiffer spring perimeter element provides the rigidity need for comfortable seating and wear resistance. | 07-15-2010 |
20100180383 | LOW-PROFILE MATTRESS - A low-profile mattress comprises an inner spring core having a plurality of spring coils and having an upper and lower surface. The mattress further includes a padding layer disposed on the upper surface and a quilting layer disposed over the padding layer and having an exterior layer of a liquid resistant material, wherein the innerspring core padding layer and quilting layer are dimensionally adapted to be less than eight inches in height. | 07-22-2010 |
20100180416 | METHOD OF MANUFACTURING AN AGED MATTRESS ASSEMBLY - 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. | 07-22-2010 |
20100263130 | MATTRESS CENTER RIDGE COMPENSATOR - A mattress includes reduced-firmness materials along a central region thereof in order to mitigate the occurrence of a central ridge following repeated use of the mattress as a sleeping surface. An associated box spring may also, or instead, present a central region with reduced firmness. An adjustable member may be employed to controllably compensate for the development of a central ridge. | 10-21-2010 |
20120180225 | MATTRESS OR MATTRESS PAD WITH GEL SECTION - A mattress or a mattress pad with one or more gel sections. The gel section may provide improved support and comfort at a localized area of a mattress or a mattress pad. | 07-19-2012 |
20120186027 | MULTI-STRANDED COIL SPRING - A spring assembly including a helical coil formed from a multi-strand cord. | 07-26-2012 |
20140165292 | HYBRID MATTRESS ASSEMBLIES - Mattress assemblies that provide increased user comfort and increased airflow. The mattress assemblies generally include a multilayered mattress core including at least one coil spring layer disposed on and in direct contact with a viscoelastic foam layer. | 06-19-2014 |
20140189951 | ACTIVE AIRFLOW TEMPERATURE CONTROLLED BEDDING SYSTEMS - A climate controlled bedding system includes at least one coil spring layer; and an air supply fluidly coupled to the one or more fluid conduits. In some embodiments, a filter is disposed within a flow path of a fluid conduit. | 07-10-2014 |
