  • Patent number: 6481033
    Abstract: A mattress system offering combinations of comfort and support comprising at least two modules, positioned side-by-side along their longest dimension to define at least two recumbent user areas the modules comprising depressions accomodating removable inserts of differing firmness. The mattress system provides an immense array of combinations of firmness and support, allowing each user to adjust, to a very wide degree, the comfort, firmness and support beneath their upper body, lumbar area, and lower body. The adaptable structure of the mattress system also allows the individual user to customize his/her side of the bed and easily change his/her side of the bed as his/her preferences change. Additionally, the construction increases the longevity of the bed, because components may be replaced one at a time as deemed necessary.

  • Patent number: 6308354
    Abstract: A mattress is provided having an innerspring, at least one upholstery layer, which includes at least one foam layer, and quilt panel layers. The upholstery layer has an edged support layer, a steel wire grid laminated to the edged support layer, and a firm foam layer laminated to the steel wire grid. The steel wire grid serves to provide support and to reduce the sagging effect caused when adding additional foam layers. The firm foam layer provides support distributed even across the mattress and may be used alone or in combination with the steel wire grid.

  • Patent number: 6295674
    Abstract: A foldable springless mattress for a sleeper sofa has a hard but bendable bottom insulator pad, a first flexible foam layer adhered on top of the insulator pad, an all-natural latex rubber layer adhered on top of the first flexible foam layer, and a composite panel adhered on top of the rubber layer. The composite panel includes an intermediate layer of antimicrobial-treated fibers quilted together with a second flexible foam layer and a moisture-resistant damask fabric. This damask fabric covers all surfaces of the mattress. A process of making the foldable springless mattress includes the steps of providing the insulator pad, adhering the first flexible foam layer on top of the pad, adhering the rubber layer on top of the first flexible foam layer, and adhering the composite panel on top of the rubber layer. The composite panel is formed preliminarily by quilting the layer of antimicrobial-treated fibers together with the second flexible foam layer and the damask fabric.

  • Patent number: 6108835
    Abstract: A camping mat in which the upper surface has a plurality of air insulating chambers to provide a reduction in body heat loss of the user. The mat may be configured as either a sleeping mat or a camping chair, or combination thereof, and may be of the self-inflating type with open-cell foam inside a waterproof and airtight envelope. Two pads of flexible foam are in the envelope and the upper pad has a plurality of pad cavities or pad apertures which, upon the assembly of the mat, cause the formation of the air insulating chambers.

  • Patent number: 5669092
    Abstract: A water-tight and heat-insulating air mattress structure having an air valve and a body made up of upper and lower layers, first and second LLDPE layers, first and second aluminum foil layers, and a nylon layer sandwiched there-between. The upper layer is applied on the first LLDPE layer which can retard the encroachment of water, while the first aluminum foil layer which can prevent the heat from dissipation is laminated between the first LLDPE layer and the nylon layer. The opposite layers, the lower layer and the second LLDPE and second aluminum layers, are applied in the same order as the above layers, and thus laminating and sandwiching the nylon layer there-between to form an air mattress structure with the advantages of both water-tight and heat-insulating.
