Mattress assembly

Abstract

A mattress assembly includes a foundation that defines first and second axes oriented along the length and the width of the foundation, respectively. The mattress assembly further includes a mattress supported atop the foundation and means for securing the mattress to the foundation to inhibit sliding movement of the mattress relative to the foundation along at least one of the first and second axes.

         31 . A mattress assembly comprising:
 a foundation defining first and second axes oriented along the length and the width of the foundation, respectively;   a mattress supported atop the foundation; and   an alignment fitting extending from one of the foundation and the mattress, and a cavity defined in the other of the foundation and the mattress in which the fitting is inserted for coupling the mattress to the foundation to inhibit sliding movement of the mattress relative to the foundation along at least one of the first and second axes.   
     
     
         32 . The mattress assembly of  claim 31 , wherein the cavity is a first cavity defined in the mattress, and wherein the foundation includes a second cavity in which the fitting is anchored. 
     
     
         33 . The mattress assembly of  claim 32 , further comprising a fan positioned in one of the first and second cavities for generating an airflow through the mattress and the foundation. 
     
     
         34 . The mattress assembly of  claim 31 , wherein the fitting extends between a top surface of the foundation and a bottom surface of the mattress. 
     
     
         35 . The mattress assembly of  claim 31 , wherein the fitting includes a tapered end to facilitate insertion into the cavity. 
     
     
         36 . The mattress assembly of  claim 31 , wherein the mattress includes a viscoelastic foam. 
     
     
         37 . The mattress assembly of  claim 36 , wherein a substantial portion of the mattress is made of the viscoelastic foam. 
     
     
         38 . The mattress assembly of  claim 36 , wherein the viscoelastic foam includes a hardness of at least about 20 N and no greater than about 80 N. 
     
     
         39 . The mattress assembly of  claim 36 , wherein the viscoelastic foam includes a density of no less than about 30 kg/m 3  and no greater than about 150 kg/m 3 .
