Mattress and associated methods

Abstract

A mattress may include a support base. The support base may include four adjoining border walls, a support portion enclosed within the border walls, and a transition panel above the support portion. An enclosure may be above the support base and include four adjoining enclosure walls each attached to one of the border walls, a fastener disposed on one or more of the enclosure walls, a cover, and a cavity bound by the enclosure walls, the cover, and the transition panel. A cartridge may be removably receivable within the cavity, the cartridge including layers encased within an encasement sleeve, the encasement sleeve abutting inner surfaces of at least three of the enclosure walls when received within the enclosure.

What is claimed is: 
     
         1 . A mattress, comprising:
 a support base, including:
 four adjoining border walls, 
 a support portion enclosed within the border walls, and 
 a transition panel above the support portion; 
   an enclosure above the support base, including:
 four adjoining enclosure walls each attached to one of the border walls, 
 a fastener disposed on one or more of the enclosure walls, 
 a cover, and 
 a cavity bound by the enclosure walls, the cover, and the transition panel; and 
 a cartridge removably receivable within the cavity, the cartridge including layers encased within an encasement sleeve, the encasement sleeve abutting inner surfaces of at least three of the enclosure walls when received within the enclosure. 
   
     
     
         2 . The mattress of  claim 1 , wherein the cartridge layers comprise foam layers. 
     
     
         3 . The mattress of  claim 1 , wherein the cartridge layers comprise one or more layers of foam and one or more layers of microcoils. 
     
     
         4 . The mattress of  claim 1 , wherein a foam encasement is not included in the cartridge. 
     
     
         5 . The mattress of  claim 1 , wherein the fastener is a zipper, and the zipper is near an upper edge of three or four of the enclosure walls. 
     
     
         6 . The mattress of  claim 1 , wherein the encasement sleeve abuts inner surfaces of four enclosure walls when received within the enclosure. 
     
     
         7 . The mattress of  claim 1 , wherein the cover includes a pillow top. 
     
     
         8 . The mattress of  claim 1 , wherein the transition panel comprises foam. 
     
     
         9 . The mattress of  claim 1 , wherein the support base comprises a base panel comprising foam below the support portion. 
     
     
         10 . The mattress of  claim 1 , wherein the cartridge is configured to be roll packed. 
     
     
         11 . The mattress of  claim 1 , wherein the cartridge has a cartridge length from a first wall provided by the encasement sleeve to a second wall provided by the encasement sleeve and a cartridge width from a third wall provided by the encasement sleeve to a fourth wall provided by the encasement sleeve, and the support base has a support base width from a first border wall to a second border wall and a support base length from a third border wall to a fourth border wall, the cartridge width is substantially the same as the support base width, and the cartridge length is substantially the same as the support base length. 
     
     
         12 . The mattress of  claim 11 , wherein the cartridge is configured to be roll packed. 
     
     
         13 . The mattress of  claim 11 , wherein the cartridge layers comprise one or more layers of foam and one or more layers of microcoils. 
     
     
         14 . The mattress of  claim 1 , wherein the support portion comprises coils. 
     
     
         15 . A method, comprising:
 arranging a support base such that a transition panel is above a support portion within adjoining border walls;   positioning a cartridge within a cavity of an enclosure above the transition panel, the enclosure including adjoining enclosure walls bounding the cavity and each attached to one of the border walls, the cartridge including layers encased within an encasement sleeve, the encasement sleeve abutting inner surfaces of at least three enclosure walls of the enclosure when positioned within the enclosure; and   fastening the enclosure to a closed position with the cartridge within the cavity.   
     
     
         16 . The method of  claim 15 , comprising:
 before the positioning step, unrolling the cartridge from a first roll packed configuration.   
     
     
         17 . The method of  claim 16 , comprising:
 before the arranging step, unrolling the support base and enclosure from a second roll packed configuration separate from the first roll packed configuration.   
     
     
         18 . The method of  claim 17 , wherein the fastening step includes zipping a cover to one or more of the enclosure walls. 
     
     
         19 . The method of  claim 15 , comprising:
 before the arranging step, unrolling the support base and enclosure from a roll packed configuration.   
     
     
         20 . The method of  claim 15 , wherein the fastening step includes zipping a cover to one or more of the enclosure walls.
