Mattress assemblies

Abstract

A mattress includes a bottom mattress assembly including a bottom core and a receptacle at least partially surrounding the bottom core and protruding a first distance beyond a top of the bottom core. The mattress also includes a top mattress assembly insertable into the receptacle including a top core and a top cover. The mattress also includes a mattress cover including: a cover bottom including a base beneath the bottom core, and a cover top including a top positionable over the top cover of the top mattress assembly and sides extending around at least a portion of the top cover. A first portion of the sides of the cover top is adjacent the sides of the top cover and a second portion of the sides of the cover top is adjacent the receptacle. The mattress also includes a fastener that selectively couples the cover bottom to the cover top.

What is claimed is: 
     
         1 . A mattress, comprising:
 a bottom mattress assembly including:
 a bottom core; 
 a receptacle at least partially surrounding the bottom core and protruding a first distance beyond a top of the bottom core; 
   a top mattress assembly insertable into the receptacle and including:
 a top core; and 
 a top cover at least partially surrounding the top core; 
   a mattress cover including:
 a cover bottom including a base beneath the bottom core of the bottom mattress assembly; 
 a cover top including a top positionable over the top cover of the top mattress assembly and sides extending around at least a portion of the top cover, wherein a first portion of the sides of the cover top is adjacent the sides of the top cover and a second portion of the sides of the cover top is adjacent the receptacle; and 
 a fastener that selectively couples the cover bottom to the cover top. 
   
     
     
         2 . The mattress of  claim 1 , wherein the first distance is less than a thickness of the top core. 
     
     
         3 . The mattress of  claim 2 , wherein the cover bottom further includes sides extending around the sides of the receptacle of the bottom mattress assembly and protruding a second distance beyond a top of the bottom core. 
     
     
         4 . The mattress of  claim 3 , wherein the second distance the sides of the cover bottom protrude beyond the top of the bottom core is less than the first distance the sides of the receptacle protrude beyond the top of the bottom core. 
     
     
         5 . The mattress of  claim 3 , wherein a side of the receptacle is secured to a side of the cover bottom. 
     
     
         6 . The mattress of  claim 1 , wherein another fastener secures the receptacle to the bottom core. 
     
     
         7 . The mattress of  claim 1 , wherein the receptacle is laterally adjustable. 
     
     
         8 . The mattress of  claim 1 , wherein the receptacle includes a base extending at least partially beneath the bottom core and sides extending at least partially around an outer periphery of the bottom core. 
     
     
         9 . A mattress, comprising:
 a bottom mattress assembly including a receptacle:   a top mattress assembly insertable into the receptacle; and   a mattress cover including:
 a cover bottom including a base beneath the bottom mattress assembly; 
 a cover top including a top positionable over a top of the top mattress assembly and sides extending around at least a portion of the top mattress assembly, wherein a first portion of the sides of the cover top is adjacent the sides of the top mattress assembly and a second portion of the sides of the cover top is adjacent the bottom mattress assembly; and 
 a fastener that selectively couples the cover bottom to the cover top. 
   
     
     
         10 . The mattress of  claim 8 , wherein bottom mattress assembly further comprises a bottom core positioned in the receptacle. 
     
     
         11 . The mattress of  claim 10 , wherein the receptacle extends a first distance beyond a top of the bottom core. 
     
     
         12 . The mattress of  claim 10 , wherein the receptacle is laterally adjustable. 
     
     
         13 . The mattress of  claim 9 , wherein the top mattress assembly comprises a top core and a top cover at least partially surrounding the top core. 
     
     
         14 . A method for assembling a mattress, comprising:
 providing a bottom mattress assembly with a receptacle at least partially surrounding a bottom core;   inserting a base portion of a top mattress assembly including sides extending around an outer periphery of the top mattress assembly into the receptacle of the bottom mattress assembly; and   securing a cover top on the top mattress assembly to a cover bottom on the bottom mattress assembly, wherein a first portion of sides of the cover top are adjacent the sides of the top mattress assembly and a second portion of the sides of the cover top are adjacent sides of the receptacle.   
     
     
         15 . The method of  claim 14 , further comprising:
 laterally tightening the receptacle around a periphery of the top mattress assembly.   
     
     
         16 . The method of  claim 14 , further comprising: placing a cover top over a top of the top mattress assembly. 
     
     
         17 . The method of  claim 16 , wherein providing the bottom mattress assembly comprises providing a bottom mattress assembly with which a cover bottom has been assembled. 
     
     
         18 . The method of  claim 14 , further comprising:
 selecting the bottom mattress assembly from a plurality of bottom mattress assemblies of different configurations.   
     
     
         19 . The method of  claim 14 , further comprising:
 selecting the top mattress assembly from a plurality of top mattress assemblies of different configurations.   
     
     
         20 . The method of  claim 19 , wherein selecting the top mattress assembly comprises selecting at least two top mattress assemblies to be arranged side-by-side over the bottom mattress assembly.
