Abstract

A multilayer mattress comprising a top polyurethane polyether reticulated foam layer; a middle polyurethane polyether reticulated foam layer; and a bottom support layer. The top layer has an open-cell structure, a thickness of 1.5-5 cm, a compression resistance of 1-5.5 kPa and a resilience of 40-55%; whereas the middle layer has an open-cell structure, a thickness of 2.5-7.5 cm, a compression resistance of 1-5.5 kPa and a resilience of 1-15%.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A multilayer mattress comprising:
 a top polyurethane polyether reticulated foam layer, having an open-cell structure, a thickness of 1.5-5 cm, a compression resistance of 1-5.5 kPa and a resilience of 40-55%;   a middle polyurethane polyether reticulated foam layer having an open-cell structure, a thickness of 2.5-7.5 cm, a compression resistance of 1-5.5 kPa and a resilience of 1-15%; and   a bottom support layer.   
     
     
         2 . The multilayer mattress according to  claim 1 , wherein the top foam layer has a thickness of 2 cm. 
     
     
         3 . The multilayer mattress according to  claim 1 , wherein the top foam layer has a compression resistance of 1.3-5.5 kPa. 
     
     
         4 . The multilayer mattress according to  claim 3 , wherein the top foam layer has a compression resistance of 3.5-5.5 kPa. 
     
     
         5 . The multilayer mattress according to  claim 4 , wherein the top foam layer has a compression resistance of 3.5 kPa. 
     
     
         6 . The multilayer mattress according to  claim 1 , wherein the top foam layer has a resilience of 50%. 
     
     
         7 . The multilayer mattress according to  claim 1 , wherein the middle foam layer has a thickness of 4-6 cm. 
     
     
         8 . The multilayer mattress according to  claim 7 , wherein the middle foam layer has a thickness of 4 cm. 
     
     
         9 . The multilayer mattress according to  claim 1 , wherein the middle foam layer has a compression resistance of 1-3 kPa. 
     
     
         10 . The multilayer mattress according to  claim 9 , wherein the middle foam layer has a compression resistance of 1.24 kPa. 
     
     
         11 . The multilayer mattress according to  claim 1 , wherein the middle foam layer has a resilience of 7%. 
     
     
         12 . The multilayer mattress according to  claim 1 , wherein the cells in the structure of the middle layer are opened to a lesser extent compared to the cells in the structure of the top layer. 
     
     
         13 . The multilayer mattress according to  claim 1 , wherein it has a water vapor resistance of 96-97 m 2  Pa/W. 
     
     
         14 . The multilayer mattress according to  claim 1 , wherein it has a thermal resistance of 1.2-1.4 m 2 K/W. 
     
     
         15 . The multilayer mattress according to  claim 1 , wherein it has a water vapor permeability index greater than 0.8.
