Plastic mattress foundation having a 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 foundation constructed substantially of plastic material, comprising: 
 a. a generally planar and essentially rigid top surface having an upper side and a lower side; and    b. at least one essentially rigid 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 three dimensional architectural features formed therein wherein the architectural features mimic a pattern and tactile feel substantially comparable to quilted surface of a companion mattress.    
     
     
         2 . (Cancelled).  
     
     
         3 . The mattress foundation of  claim 1 , including a headboard tangentially extending vertically along one end of the foundation.  
     
     
         4 . The mattress foundation of  claim 3 , wherein the headboard is made of substantially plastic material.  
     
     
         5 . The mattress foundation of  claim 4 , wherein an outer surface of the headboard, includes a pattern.  
     
     
         6 . The mattress foundation of  claim 1 , wherein a pattern is formed on at least a portion of the upper side of the top surface.  
     
     
         7 . The mattress foundation of  claim 1 , including at least one ground support member.  
     
     
         8 . The mattress foundation of  claim 7 , wherein the ground support is made of substantially plastic material.  
     
     
         9 . The mattress foundation of  claim 8 , wherein an outer surface of the ground support includes a pattern.  
     
     
         10 . 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 three dimensional features formed therein causing the outer surface to mimic a quilting pattern substantially comparable to quilting pattern on a companion mattress; 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.    
     
     
         11 . A mattress foundation assembly comprising, 
 a. an essentially rigid plastic top panel, and    b. at least one essentially rigid plastic side wall extending along at least a portion of a perimeter of the plastic top panel and depending downward from the plastic top panel, wherein an outer surface of the plastic side wall includes first three dimensional features sized and shaped to mimic a quilting pattern on a companion mattress.    
     
     
         12 . The mattress foundation assembly of  claim 11 , wherein the plastic side wall includes a panel interfitted onto the outer surface of the plastic side wall, and an outer surface of the panel includes the first three dimensional features.  
     
     
         13 . The mattress foundation assembly of  claim 11 , wherein the first three dimensional features are molded into the panel.  
     
     
         14 . The mattress foundation assembly of  claim 11 , wherein the first three dimensional features are molded into the plastic side wall.  
     
     
         15 . The mattress foundation assembly of  claim 11  including an aperture for a drawer.  
     
     
         16 . The mattress foundation assembly of  claim 15  including a drawer slidably interfitted within the aperture, the drawer having an outer side, the outer side of the drawer including second three dimensional features substantially the same as the first three dimensional features of the plastic side wall.  
     
     
         17 . The mattress foundation assembly of  claim 11 , wherein the rigid top panel includes an outer surface and the outer surface includes second three dimensional features and an outer periphery portion substantially devoid of the second three dimensional architectural features.  
     
     
         18 . The mattress foundation assembly of  claim 11 , wherein the outer periphery portion of the outer surface of the rigid top panel is substantially devoid of substantially any three dimensional features, including the first and second three dimensional features.
