Seating cushion pad for a chair

Abstract

A seat cushion pad is provided that includes a base with an array of coiled springs positioned on an upper surface of the base. A machine spun fiber foam layer rests on top of the array of coiled springs with a high-density foam sidewall surrounding the array of coiled springs and resting on the top surface of the base. An upper base layer made of high density foam rests on the sidewall with a pliable and elastic low density polyurethane foam layer pad on top of the upper base layer. A material cover encloses the high-density foam sidewall, the upper base layer, and the low density polyurethane foam layer pad.

1 . A seating cushion pad comprising:
 a base;   an array of coiled springs positioned on an upper surface of the base;   a machine spun fiber foam layer that provides air flow channels rests on top of the array of coiled springs;   a high-density foam sidewall surrounding the array of coiled springs and resting on the top surface of the base;   an upper base layer made of high density foam resting on the sidewall;   a pliable and elastic low density polyurethane foam layer pad that rests on top of the upper base layer; and   a material cover that encloses the high-density foam sidewall, the upper base layer, and the low density polyurethane foam layer pad.   
     
     
         2 . The seating cushion pad of  claim 1  wherein the base is made of plywood or a composite material, and the base is an attachment point for chair legs attached to a lower face of the base. 
     
     
         3 . The seating cushion pad of  claim 1  wherein the coiled springs are hand tied. 
     
     
         4 . The seating cushion pad of  claim 1  wherein the machine spun fiber foam layer is formed as a mesh of foam strands of fiber. 
     
     
         5 . The seating cushion pad of  claim 1  wherein the fiber used in the machine spun fiber foam layer is a sparse unwoven polymer comprising cellulose, Nylon, or spun polypropylene fiber. 
     
     
         6 . The seating cushion pad of  claim 1  wherein the fiber used in the machine spun fiber foam layer is formed of thermoplastic elastomers. 
     
     
         7 . The seating cushion pad of  claim 1  wherein the fiber used in the machine spun fiber foam layer is formed of thermoplastic polyester elastomer (TPEE). 
     
     
         8 . The seating cushion pad of  claim 1  wherein the high-density foam of the sidewall and upper base is formed from polyurethane polymers. 
     
     
         9 . The seating cushion pad of  claim 1  wherein the covering is a woven material made of natural or synthetic fibers, suede, leather, or a combination thereof. 
     
     
         10 . The seating cushion pad of  claim 9  wherein coverings made of suede or leather have a vent.
