Foam Mattress, Foam Topper and Method of Using the Same

Abstract

It is disclosed a foam mattress or topper to control a whole body alignment, comprising: a first foam section defining an upper surface, a lower surface, a longitudinal direction allowing for longitudinally receiving a user's body, and a plurality of mattress areas comprising: an upper body receiving area for supporting user's upper body and shoulders; a lower body receiving area for supporting user's lower body; and a middle body receiving area for supporting a user's hip; and a first lateral channel within the upper body receiving area and extending in a lateral direction normal to the longitudinal direction of the mattress, the first lateral channel thereby allowing the upper body receiving area above the first lateral channel to displace downward to provide pressure reduction and alignment for the shoulder of the user's body. These mattresses and toppers have an ultra-low pressure capable of preventing sleep disturbance caused by pressure.

 a middle body receiving area for supporting a user's hip; and 
   a first lateral channel within the upper body receiving area and extending in a lateral direction normal to the longitudinal direction of the mattress, the first lateral channel thereby allowing the upper body receiving area above the first lateral channel to displace downward to provide pressure reduction and alignment for the shoulder of the user's body.   
     
     
         2 . The foam mattress of  claim 1 , further comprising a second lateral channel within the middle body receiving area between the upper surface and the lower surface of the first foam section, and extending in the lateral direction normal to the longitudinal direction of the mattress, the second lateral channel thereby allowing the middle body receiving area above the second lateral channel to displace downward to provide pressure reduction and alignment for the hip of the user's body. 
     
     
         3 . The foam mattress of  claim 1 , further comprising a third lateral channel within the lower body receiving area defined in the first foam section and located between the upper surface and the lower surface of the first foam section, and extending in the lateral direction normal to the longitudinal direction of the mattress, the third lateral channel thereby allowing the lower body receiving area above the third lateral channel to displace downward to provide pressure reduction and alignment for the user's lower body. 
     
     
         4 . The foam mattress of  claim 3 , wherein the first foam section is symmetrical from the upper body receiving area to the lower body receiving area. 
     
     
         5 . The foam mattress of  claim 1 , further comprising:
 a pair of intermediate lateral grooves extending downward from the upper surface of the foam section within the upper body receiving area, one intermediate lateral grooves being before and adjacent to the first lateral channel and the other one being after and adjacent the first lateral channel, the intermediate lateral grooves interacting with the first lateral channel so as to assist pressure reduction and alignment for the shoulder of the user's body.   
     
     
         6 . The foam mattress of  claim 3 , further comprising:
 a pair of intermediate lateral grooves extending downward from the upper surface of the foam section within the lower body receiving area, one intermediate lateral grooves being before and adjacent to the third lateral channel and the other one being after and adjacent the third lateral channel, intermediate lateral grooves interacting with the third lateral channel so as to assist pressure reduction and alignment for the user's lower body.   
     
     
         7 . The foam mattress of  claim 1 , further comprising a second foam section for supporting the first foam section, the second foam section defining an upper surface for interfacing with the lower surface of the first foam section. 
     
     
         8 . The foam mattress of  claim 1 , wherein the upper body receiving area comprises a plurality of first lateral channels parallel one to the other and wherein the lower body receiving area lateral channel comprises a plurality of adjacent lower body receiving area lateral channels. 
     
     
         9 . The foam mattress of  claim 1 , further comprising two lateral grooves extending from the upper surface of the first foam section, wherein one lateral groove delimits the upper and middle body receiving areas, whereas the second lateral groove delimits the middle and lower body receiving areas, each lateral groove being defined by a first lateral edge and a second lateral edge at an angle from the first lateral edge. 
     
     
         10 . The foam mattress of  claim 9 , wherein the second lateral edge is at an angle of about 45 degrees from the first lateral edge. 
     
     
         11 . The foam mattress of  claim 3 , wherein each one of the first lateral channel and the second lateral channels defines a substantially hemi-elliptical cross-section area. 
     
     
         12 . The foam mattress of  claim 11 , wherein the substantially hemi-elliptical has a cross-section area of between about 0.0381 m and about 0.051 m deep; and has a radius of about 0.140 m. 
     
     
         13 . The foam mattress of  claim 3 , wherein each one of the first lateral channel and the lower body receiving area lateral channels defines a substantially hemi-circular cross-section area. 
     
     
         14 . The foam mattress of  claim 2 , wherein the second lateral channel defines a substantially hemi-elliptical cross-section area. 
     
     
         15 . The foam mattress of  claim 14 , wherein the substantially hemi-elliptical cross-section area is between about 0.0381 m to about 0.051 m deep. 
     
     
         16 . The foam mattress of  claim 15 , wherein the substantially hemi-elliptical cross-section area comprises a radius of about 0.051 m. 
     
     
         17 . The foam mattress of  claim 2 , wherein the second lateral channel defines a substantially hemi-circular cross-section area. 
     
     
         18 . The foam mattress of  claim 1 , wherein the first foam section has a thickness of about 0.051 m to about 0.381 m. 
     
     
         19 . The foam mattress of  claim 9 , further comprising a plurality of adjacent intermediate lateral grooves extending from the upper surface of the first foam section between the two lateral grooves. 
     
     
         20 .
