Mattress having reticulated viscoelastic foam

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.

1 . A foam mattress comprising a reticulated, viscoelastic foam, wherein the viscoelastic foam is comprised of at least about fifteen percent by weight of a viscoelastic polyol.  
   
   
       2 . A foam mattress as described in  claim 1 , wherein the foam mattress comprises a plurality of layers of foam, and one of the layers comprises the reticulated, viscoelastic foam.  
   
   
       3 . A mattress as described in  claim 1 , wherein the foam mattress comprises a plurality of zones of foam, and one of the zones comprises the reticulated, viscoelastic foam.  
   
   
       4 . The mattress as described in  claim 1 , wherein the mattress comprises three or more layers of foam, and an outside layer comprises the reticulated, viscoelastic foam.  
   
   
       5 . The mattress as described in  claim 4 , wherein the outside layer covers substantially the entire length and width of the mattress.  
   
   
       6 . The mattress as described in  claim 2 , wherein a second layer comprises a reticulated polyurethane foam, and the reticulated viscoelastic and reticulated polyurethane foams are adhered to each other.  
   
   
       7 . The mattress as described in  claim 1 , wherein the viscoelastic foam is comprised of about 15% to about 75% by weight of viscoelastic polyol.  
   
   
       8 . The mattress as described in  claim 1 , wherein the viscoelastic foam is comprised of about 60% to about 70% by weight of viscoelastic polyol.  
   
   
       9 . The mattress as described in  claim 2 , further wherein the mattress comprises a plurality of zones of foam.  
   
   
       10 . The mattress as described in  claim 9 , wherein the foam mattress comprises at least three layers of foam and at least three zones of foam.  
   
   
       11 . The mattress as described in  claim 10 , wherein the foam mattress has a symmetrical layer construction.  
   
   
       12 . The mattress as described in  claim 10 , wherein the foam mattress has a symmetrical zone construction.  
   
   
       13 . The mattress as described in  claim 11 , wherein the foam mattress has a symmetrical zone construction.  
   
   
       14 . The mattress as described in  claim 1 , wherein the foam mattress comprises five layers of foam, and wherein the outside layers of foam comprise latex, the layers immediately adjacent the outside layers comprise the viscoelastic foam, and a central layer comprises reticulated polyurethane foam.
