Mattress with a Vented Cover

Abstract

A mattress to support a user that includes a core positioned within an interior space formed by a cover. The cover protects the core from damage that could result from contact with liquid or debris. A vent extends through the cover to allow airflow into and out of the interior space. The vent 40 includes a plurality of pores that allow the airflow, but limit ingress of liquid and debris.

1 . A mattress to support a user comprising:
 a core that includes a first end and a second end and first and second sides that extend between the ends and are each configured to support the user;   a cover that forms an enclosed interior space to contain the core, the cover including an exterior surface that is visible to the user and an interior surface that faces towards the core; and   a vent including a plurality of pores that each extend through the cover and are positioned in an area of the cover, and a patch attached to the interior surface of the cover that extends over the area, the patch being constructed from a material that limits ingress of liquid into the interior space and allows airflow into and out of the interior space.   
     
     
         2 . The mattress of  claim 1 , further comprising a continuous seal around the patch that attaches the patch to the interior surface of the cover. 
     
     
         3 . The mattress of  claim 1 , wherein the plurality of pores range in size from about 0.30 mm to about 50 mm. 
     
     
         4 . The mattress of  claim 3 , wherein each of the plurality of pores include a common size. 
     
     
         5 . The mattress of  claim 1 , further comprising a second vent through the cover for moving air into and out of the interior space and limiting liquid from entering into the interior space, the second vent being spaced away from the vent and including a different pore density than the vent. 
     
     
         6 . The mattress of  claim 1 , wherein each of the pores includes a raised lip that extends outward beyond an exterior surface of the cover. 
     
     
         7 . The mattress of  claim 1 , wherein the core includes a body and a pillow positioned in an end-to-end configuration, the pillow including a greater height than the body. 
     
     
         8 . A mattress to support a user comprising:
 a core that includes a top surface and a bottom surface each configured to support the user;   a cover that forms an enclosed interior space to contain the core, the cover including an interior surface that faces towards the core and an exterior surface; and   a plurality of pores that each extend through the cover for moving air into and out of the interior space and limiting liquid from entering into the interior space, each of the plurality of pores including a raised lip that extends outward beyond the exterior surface of the cover.   
     
     
         9 . The mattress of  claim 8 , further comprising a patch that extends over the plurality of pores and is attached to the interior surface of the cover, the patch constructed to allow airflow into and out of the interior space. 
     
     
         10 . The mattress of  claim 8 , wherein the cover includes a vertical seam that is shorter than a height of the core. 
     
     
         11 . The mattress of  claim 9 , wherein a surface of the patch that faces the interior surface of the cover and the exterior surface of the cover have a common color. 
     
     
         12 . The mattress of  claim 8 , wherein each of the plurality of pores ranges in size from about 6 microns to about 15 microns. 
     
     
         13 . The mattress of  claim 9 , wherein the cover is constructed from PVC vinyl and the patch is constructed from PTFE. 
     
     
         14 . The mattress of  claim 8 , wherein the core includes a pillow. 
     
     
         15 . A mattress to support a user comprising:
 a core that includes a top surface and a bottom surface each configured to support the user;   a cover that forms an enclosed interior space to contain the core, the cover including an interior surface that faces towards the core and an exterior surface; and   a plurality of pores that each extend through the cover for moving air into and out of the interior space and limiting liquid from entering into the interior space, each of the plurality of pores including a size ranging from about 6 microns to about 15 microns; and.   a patch that extends over the plurality of pores and is attached to the cover, the patch constructed to allow airflow through the plurality of pores and into and out of the interior space.   
     
     
         16 . The mattress of  claim 15 , wherein the patch is attached to the interior surface of the cover. 
     
     
         17 . The mattress of  claim 15 , wherein each of the plurality of pores includes a raised lip. 
     
     
         18 . The mattress of  claim 17 , wherein the raised lips extend outward from the exterior surface of the cover. 
     
     
         19 . The mattress of  claim 15 , wherein the patch is constructed of PTFE material. 
     
     
         20 . The mattress of  claim 15 , wherein the core includes a body and a pillow that are positioned to contact each other in a non-overlapping arrangement.
