Adjustable cushion device

Abstract

This disclosure relates to a cushion and more particularly to a pillow providing cervical alignment by way of a cervical spine support structure that is positioned along a major axis of the pillow, and that can be rotated around the major axis. The pillow utilizes one or more of the following features: 1) a dimensionally correct platform for the proper sleep posture of a majority of body types on a wide array of mattress types; 2) A non-crush zone integrated cervical support roll which can be adjusted for extended durations of supportive comfort. (The roll—in and of itself—is unique compared to the standard of care because of its foam densities and its semi-hollowed out section); and 3) A sleep posture platform with a side sleeping position and a back-sleeping position. The pillow standardizes care by placement of the support roll inside a dimensionally correct platform using different materials.

What is claimed is: 
     
         1 . A cushion comprising:
 a top side, a bottom side, a cylindrical compartment; and   a cylindrical cervical spine support disposed in the cylindrical compartment, the cylindrical cervical spine support running along a major axis and comprising two or more segments of material with different densities or geometries also running along the major axis;   the cervical spine support being configured to freely rotate in relation to the cushion around the major axis within the cylindrical compartment.   
     
     
         2 . The cushion of  claim 1 , wherein the cushion is configured to have sufficient clearance for the adjustable cervical spine support to freely rotate within the cylindrical compartment. 
     
     
         3 . The cushion of  claim 1 , wherein the cylindrical cervical spine support is free of protrusions. 
     
     
         4 . The cushion of  claim 1 , wherein the cylindrical compartment is free of indentations corresponding to protrusions, if present, on the cylindrical cervical spine support. 
     
     
         5 . The cushion of  claim 1 , wherein a knob is coupled to the cervical spine support and the knob is configured to facilitate rotation of the cervical spine support. 
     
     
         6 . The cushion of  claim 1 , wherein the two or more segments of material comprise a firm segment and a soft segment, as determined by the Indentation Load Deflection test. 
     
     
         7 . The cushion of  claim 1 , wherein the two or more segments of material are of the same geometry but of different densities. 
     
     
         8 . The cushion of  claim 1 , wherein the two or more segments of material are of different internal geometries. 
     
     
         9 . The cushion of  claim 1 , wherein the cylindrical compartment runs between opposite sides of the cushion. 
     
     
         10 . The cushion of  claim 1 , wherein the cylindrical compartment and the cylindrical cervical spine support have a 1 micrometer to 1 centimeter circumferential difference. 
     
     
         11 . The cushion of  claim 1 , further comprising:
 a head well portion having a lower surface with a depth of 0.8 to 2.7 inches from a top side of the pillow;   wherein the pillow has a total thickness of 5 to 6.25 inches from the top side of the pillow to the bottom side of the pillow.   
     
     
         12 . The cushion of  claim 1 , wherein the cervical spine support is configured to rotate around the major axis while in continuous contact with the cylindrical compartment. 
     
     
         13 . A pillow comprising:
 a cervical spine support running along a major axis and comprising two or more segments of material having different densities or geometries, the two or more segments also running along the major axis;   the cervical spine support being coupled in a configuration to rotate around the major axis in relation to the pillow;   the cervical spine support having a substantially cylindrical exterior shape free of protrusions.   
     
     
         14 . The pillow of  claim 13 , wherein the two or more segments of the cervical spine support are joined by an adhesive. 
     
     
         16 . The pillow of  claim 13 , wherein at least one of the two or more segments has an interior cut-out running along the at least one segment in a direction of the major axis. 
     
     
         17 . The pillow of  claim 13 , wherein a knob is coupled to the cervical spine support and the knob is configured to facilitate rotation of the cervical spine support. 
     
     
         18 . A pillow comprising:
 a cervical spine support running along a major axis and comprising two or more segments of material having different densities, the two or more segments also running along the major axis; and   a cylindrical compartment in the pillow;   the cervical spine support being configured to rotate around the major axis in relation to the pillow while in continuous contact with a cylindrical compartment of the pillow.   
     
     
         19 . The pillow of  claim 18 , wherein the cylindrical cervical spine support is free of protrusions. 
     
     
         20 . The pillow of  claim 19 , wherein the cylindrical compartment and the cylindrical cervical spine support have a 1 micrometer to 1 centimeter circumferential difference.
