Mattress with attachable cores

Abstract

A mattress including a core having a corner positioned along a top surface of the core and extending along a head portion, a foot portion, and first and second side portions of the core, a perimeter rail structure that extends around a perimeter of the core to surround the core. The core is attached via the corner to the perimeter rail structure along the perimeter rail structure.

What is claimed is: 
     
         1 . A mattress comprising:
 a core having a corner positioned along a top surface of the core and extending along a head portion, a foot portion, and first and second side portions of the core   a perimeter rail structure that extends around a perimeter of the core to surround the core; and   wherein the core is attached via the corner to the perimeter rail structure along the perimeter rail structure.   
     
     
         2 . The mattress of  claim 1 , further comprising a foam layer positioned at a top surface of the mattress above the core and the perimeter rail structure. 
     
     
         3 . The mattress of  claim 2 , further comprising a plurality of straps that are each positioned between a top surface of the perimeter rail structure and a bottom surface of the foam layer. 
     
     
         4 . The mattress of  claim 3 , wherein the plurality of straps attach the perimeter rail structure to the corner. 
     
     
         5 . The mattress of  claim 1 , wherein the mattress is configured to be compressed and rolled, and in a compressed and rolled position, the attachment of the core to the perimeter rail structure maintains a desired positioning of the core. 
     
     
         6 . The mattress of  claim 1 , wherein the core is one or more air chambers. 
     
     
         7 . The mattress of  claim 6 , wherein the corner includes a seam that extends outwardly from the top surface of the core. 
     
     
         8 . The mattress of  claim 7 , wherein a plurality of straps connects the core to the perimeter rail structure. 
     
     
         9 . The mattress of  claim 1 , wherein the core is one or more foam layers. 
     
     
         10 . The mattress of  claim 1 , wherein the perimeter rail structure includes an inverted foam tub that surrounds the core. 
     
     
         11 . A mattress comprising:
 one or more air chambers;   a perimeter rail structure including a head portion, a foot portion, and first and second side portions, wherein the perimeter rail structure is configured to extend around a perimeter of the one or more air chambers to surround the one or more air chambers; and   one or more anchors that connect the one or more air chambers to the perimeter rail structure.   
     
     
         12 . The mattress of  claim 11 , wherein each of the one or more air chambers includes a seam positioned along a top surface of the air chamber and extending outwardly from the air chamber along a head portion, a foot portion, and first and second side portions of the air chamber. 
     
     
         13 . The mattress of  claim 11 , wherein the one or more anchors connect the perimeter rail structure to the one or more air chambers at the seam. 
     
     
         14 . The mattress of  claim 12 , wherein the one or more anchors include a plurality of straps positioned around the perimeter of the one or more air chambers and extend between the seam and the perimeter rail structure. 
     
     
         15 . The mattress of  claim 14 , wherein each of the plurality of straps are each attached between a top surface of the perimeter rail structure and a bottom surface of a foam layer. 
     
     
         16 . The mattress of  claim 11 , wherein the anchors are positioned along a length and along a width of the air chamber. 
     
     
         17 . The mattress of  claim 11 , wherein the one or more air chambers includes a first air chamber and a second air chamber that extend from a head of the mattress to a foot of the mattress, the mattress further comprising a pump system having one or more air pumps fluidly connected to the first and second air chambers, wherein the pump system is configured to inflate the first and second air chambers. 
     
     
         18 . A method of assembling a mattress assembly comprising:
 connecting a core to a perimeter rail structure;   compressing and packaging a compressed mattress including the core and perimeter rail structure; and   expanding the compressed mattress while the core remains secured to the perimeter rail structure.   
     
     
         19 . The method of  claim 18 , wherein the core is connected to the perimeter rail structure via a corner positioned along a top surface of the core. 
     
     
         20 . The method of  claim 18 , wherein the core is an air chamber that has a seam extending from the core, and the core is connected to the perimeter rail structure at the seam of the air chamber extending along a top surface of the air chamber.
