Benefits of technology

[0005] Accordingly, it is an object of the present invention to overcome the foregoing drawbacks and to provide a foam mattress that includes a reticulated, viscoelastic foam. The mattress may have multiple zones and multiple layers. The reticulated nature of the viscoelastic foam allows a user to enjoy the benefits of the softness and conformability of a viscoelastic foam and also an unprecedented breathability.

Problems solved by technology

While viscoelastic foam is very popular for use as a mattress or component thereof, a major drawback to it is its inability to “breathe”.
A person may overheat and excessively perspire, because there is insufficient ventilation in the foam to allow air and moisture flow.
Also, the slow recovery aspect of the foam may make turning over difficult or getting out of a bed difficult.

Embodiment Construction

[0010] The foam mattress discussed herein include the use of a reticulated, viscoelastic foam alone and as a component in a composite mattress. By the process of reticulation, a viscoelastic foam can achieve enhanced ventilation properties, thereby making it more attractive for use as a mattress or a part thereof.

[0011] For the purposes of discussion herein, the term “viscoelastic foam” means foam formed using a viscoelastic polyol, and specifically at least about 15% by weight of the viscoelastic polyol in the finished foam. Less than about 15% by weight of viscoelastic polyol does not process well, and it is believed that the resulting foam does not have significant viscoelastic properties. Weight percent ranges of viscoelastic polyol in the finished foam include about 15% to about 75%, and, for a further example, about 60% to about 70%.

[0012] The term “reticulated viscoelastic foam” means a viscoelastic foam that has been subjected to a reticulation process. Reticulation is a m...

Abstract

A foam mattress includes a reticulated, viscoelastic foam that makes up the mattress in whole or in part. The reticulated nature of the viscoelastic foam allows a user to enjoy the benefits of softness and conformability of a viscoelastic foam and also an improved breathability. The foam mattress may include a plurality of zones of foam and / or a plurality of layers of foam, where one of the layers may be reticulated urethane for improved breathability and humidity resistance, as well as heat dissipation.

Description

[0001] The present invention relates to foam mattresses, and specifically foam mattresses made, at least in part, from reticulated, viscoelastic foam. BACKGROUND OF THE INVENTION [0002] Foam mattresses generally have been well known for many years. Standard polyurethane foam materials provide good cushion. The specific polyurethane material may be varied to make a mattress softer or firmer. Traditional polyurethane foam mattresses are known for their springy and bouncy nature. [0003] Another well-known material for use in foam mattresses is viscoelastic foam. This foam, also referred to as “memory / slow recovery” foam, has low resilience and naturally shapes or conforms to a person's body. This particular foam material is also effective to dampen sound and vibration. While viscoelastic foam is very popular for use as a mattress or component thereof, a major drawback to it is its inability to “breathe”. A person may overheat and excessively perspire, because there is insufficient vent...
