Abstract

A mattress with a top section that extends beyond the vertical sides of a main or base section. The top section includes a firmer or reinforced outer portion that surrounds a softer or less resilient inner portion. A cover encloses the top section and base section, thereby securing them together. The softer inner portion includes a plurality of foam layers, where the layers have different firmness.

That which is claimed: 
     
         1 . A device comprising
 a base portion, a top portion, and a cover where the base portion comprises side borders, where the side borders are vertical walls, where the base portion comprises one or more foam layers,   where the top portion comprises an inner section and a top border member, where the top portion extends beyond the side borders of the base portion, where the top border member bounds the inner section on four sides, where portions of the inner section and top border member form a top sleep surface,   where the inner section comprises a plurality of layers of foam, where the layers of foam further from the top sleep surface are firmer than the layers of foam closer to the top sleep surface, where the inner section comprises no glue,   where the cover encloses the base portion and the top portion, where the cover secures the top portion to the base portion; where the cover further encloses the inner section and the top border member, where the cover helps retain the inner section within the top border member.   
     
     
         2 . The device of  claim 1 , where the top border member is firmer than the inner section. 
     
     
         3 . The device of  claim 1 , where the top border member comprises an inner vertical wall, where the vertical wall is adjacent to the inner section. 
     
     
         4 . The device of  claim 1 , where the top border member comprises an outer curved wall. 
     
     
         5 . A mattress comprising
 a base portion, a top portion, and a cover,   where the base portion comprises side borders,   where the top portion comprises an inner section and a top border member, where the top portion extends beyond the side borders of the base portion, where the top border member bounds the inner section on four sides,   where the inner section comprises a plurality of layers of foam, where at least one of the layers of foam of the inner section is firmer than another layer of foam of the inner section, where the inner section comprises no glue,   where the cover encloses the base portion and the top portion, where the cover secures the top portion to the base portion; where the cover further encloses and restrains the inner section and the top border member,   where the top border member is firmer than the inner section, where the top border member comprises an inner vertical wall and an outer curved wall, where the vertical wall is adjacent to the inner section.   
     
     
         6 . The mattress of  claim 5 , where the side borders of the base portion are vertical walls. 
     
     
         7 . The mattress of  claim 5 , where the base portion comprises a layer of foam material. 
     
     
         8 . The mattress of  claim 5 , where the base portion comprises a plurality of layers of foam material. 
     
     
         9 . A mattress comprising
 a base portion and a top portion,   where the base portion comprises side borders, where the top portion and base portion are secured together,   where the top portion comprises an inner section and a top border member, where the top portion extends beyond the side borders of the base portion, where the inner section has one or more sides, a top, and a bottom, where the top border member bounds the sides of the inner section.   
     
     
         10 . The mattress of  claim 9 , where the top border member is firmer than the inner section. 
     
     
         11 . The mattress of  claim 9 , where the top border member comprises an inner vertical wall, where the vertical wall is adjacent to the inner section. 
     
     
         12 . The mattress of  claim 9 , where the top border member comprises an outer curved wall. 
     
     
         13 . The mattress of  claim 9 , further comprising a cover, where the cover encloses the base portion and the top portion, where the cover secures the top portion to the base portion. 
     
     
         14 . The mattress of  claim 9 , where the cover further encloses and restrains the inner section and the top border member. 
     
     
         15 . The mattress of  claim 9 , where the side borders are vertical walls. 
     
     
         16 . The mattress of  claim 9 , where the base portion comprises one or more foam layers. 
     
     
         17 . The mattress of  claim 9 , where the inner section comprises a plurality of layers of foam material. 
     
     
         18 . The mattress of  claim 17 , where at least one of the layers of foam material of the inner section is firmer than another layer of foam material of the inner section. 
     
     
         19 . The mattress of  claim 17 , where adjacent layers of foam material of the inner section have a different firmness. 
     
     
         20 . The mattress of  claim 9 , where inner section comprises no glue.
