Plastic mattress foundation having sculpted exterior surface

Abstract

A mattress foundation is constructed substantially of plastic material. The foundation is defined by a semi-rigid cavity including a generally flat top surface, at least one downward depending sidewall, and at least a portion of an outer surface of the sidewall having a pattern formed thereon. Optional ground support members retain the foundation in a substantially horizontal orientation. An outer surface of one or more of the ground support members has a pattern formed thereon. An outer surface of an optional headboard may have a pattern formed thereon. A portion of an upper side of the top surface may have a pattern formed thereon. The pattern formed on the sidewall, the top surface, the ground support, or the headboard may give a quilted appearance to the foundation. The pattern may be three-dimensional or substantially flat. The pattern may be integral with the foundation or attached thereto.

1 . A mattress assembly constructed substantially of plastic material, comprising: 
 a. a mattress foundation comprising: 
 i. a generally planar and essentially rigid top surface having an upper side and a lower side; and  
 ii. at least one essentially rigid sidewall, having a lower edge, the sidewall extending substantially along the perimeter of the lower side of the top surface, depending downward from the top surface, defining a cavity, wherein an outer surface of the sidewall includes a pattern; and  
   b. a frame assembly comprising a plurality of ground support members supporting the foundation, depending downward from the lower edge of the at least one sidewall, holding the foundation above ground, and maintaining the top surface in a substantially horizontal orientation.    
     
     
         2 . The assembly of  claim 1 , wherein the pattern is substantially planar.  
     
     
         3 . The assembly of  claim 1 , wherein the pattern is substantially three-dimensional.  
     
     
         4 . The assembly of  claim 1 , including a headboard tangentially extending vertically along one end of the foundation.  
     
     
         5 . The assembly of  claim 4 , wherein the headboard is made of substantially plastic material.  
     
     
         6 . The assembly of  claim 5 , wherein an outer surface of the headboard, includes a pattern.  
     
     
         7 . The assembly of  claim 1 , wherein a pattern is formed on at least a portion of the upper side of the top surface.  
     
     
         8 . The assembly of  claim 1 , including at least one ground support member.  
     
     
         9 . The assembly of  claim 8 , wherein the ground support is made of substantially plastic material.  
     
     
         10 . The assembly of  claim 9 , wherein an outer surface of the ground support includes a pattern.
