AI Technical Summary

Benefits of technology

The present invention aims to provide a mattress that minimizes both average and maximum peak pressure to reduce the occurrence of bed sores and promote comfort. It also helps to keep the user from falling off the support.

Problems solved by technology

Such pressure points can be sufficiently high to cut off or restrict capillary blood flow, pinch nerves, or otherwise provide uncomfortable and medically undesirable conditions.

example

[0035]A mattress was tested having the layer thickness specified herein (three inch top layer, three inch intermediate layer and two inch bottom layer) and layers of progressively higher IFD. The mattress had an intermediate layer of high resilience foam with resilience factor of fifty-five percent and an IFD in the range of twenty-five to thirty-five, and with a density of 2.5 to 3.5 pounds per cubic foot. While prior art mattresses have high performance in average and maximum pressure, the mattress of this test, including the adjusted parameters described above, exhibited unexpected and significantly higher performance than the prior art. In particular, prior art mattresses disclosed above have been tested to show an average pressure of between 23.99 and 24.36, with a maximum or peak pressure of between 91.68 and 95.87 (all measurements in millimeters of mercury). The mattress of this invention was independently tested and found to achieve an average pressure of 17.72 with a maxim...

Abstract

A body support such as a mattress is provided formed of a top layer, an intermediate layer and a base layer. Optional side supports are also provided. Each of these layers and optional side supports are formed of different polyurethane and / or latex foam compositions. Maximum and average peak pressures are minimized by having the intermediate layer of the mattress or other body support be formed of high resilience foam, such as foam with between forty-five and sixty-five percent resilience factor. This intermediate layer is also provided with a greater density than typical prior art body supports, with a density of between 2.5 and 3.5 pounds per cubic foot.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims benefit under Title 35, United States Code §119(e) of U.S. Provisional Application No. 61 / 896,299 filed on Oct. 28, 2013.FIELD OF THE INVENTION[0002]The following invention relates to mattresses and other cushions for beds, chairs and other structures upon which at least portions of a body are able to rest. More particularly, this invention relates to mattresses and other cushions formed of multiple layers of polyurethane and / or latex foam having characteristics which minimize peak pressure when a user rests upon the mattress.BACKGROUND OF THE INVENTION[0003]Mattresses, seat cushions and other body supports are provided both for comfort and therapeutic purposes. Such supports are generally referred to herein as mattresses even when they are utilized as a seat cushion or other body support on a structure other than a bed. One form of mattress is formed of a mass of one or more layers of foam. Materials from which su...
