Foam pillows

Abstract

An improved foam pillow including multiple foam layers, with one or more of the layers including multiple channels designed to reduce the firmness of the layer, as well as enhance cooling air flow through the pillow, thereby increasing comfort to the user by approximating the feel of a down pillow. In some examples, the improved foam pillow includes a single unified top layer equipped with channels running through its center, and optional additional layers for height adjustment. In some further examples, the improved foam pillow includes multiple layers made from different types of foam to achieve cost savings. In still further examples, channels are provided in multiple layers to maintain a desired comfort and feel.

         2 . The pillow of  claim 1 , further comprising one or more layers of foam possessing a top surface and a bottom surface, disposed so that the top surface of one of the one or more layers is beneath and in contact with the bottom surface of the second layer of foam, and any additional layers of the one or more layers are disposed below the one of the one or more layers that is in contact with the bottom surface of the second layer of foam. 
     
     
         3 . The pillow of  claim 1 , wherein the first layer and second layer are made from different types of foam. 
     
     
         4 . The pillow of  claim 3 , wherein the first layer of foam is made from memory foam. 
     
     
         5 . The pillow of  claim 1 , wherein the channels on the top surface of the second layer are shaped and arranged so as to allow air to flow through the pillow. 
     
     
         6 . The pillow of  claim 1 , wherein the bottom surface of the first layer of foam possesses a plurality of channels. 
     
     
         7 . The pillow of  claim 6 , wherein the channels on the bottom surface of the first layer of foam and on the top surface of the second layer of foam are shaped and arranged so as to allow air to flow through the pillow. 
     
     
         8 . The pillow of  claim 1 , wherein the first layer of foam possesses a plurality of vertical channels disposed so that each of said vertical channels runs between the top surface and the bottom surface of the first layer of foam. 
     
     
         9 . The pillow of  claim 8 , wherein the first layer of foam is approximately two inches to four inches in height. 
     
     
         10 . The pillow of  claim 9 , wherein the second layer of foam is approximately one to three inches in height. 
     
     
         11 . A foam pillow, comprising:
 a foam layer constructed of memory foam and possessing a plurality of channels running through the center of the foam layer so as to facilitate a flow of air, the foam layer sized so as to fit within a standard-sized pillowcase and being approximately four to six inches in height.   
     
     
         12 . The foam pillow of  claim 11 , further comprising one or more additional foam layers disposed below the memory foam layer. 
     
     
         13 . The foam pillow of  claim 12 , wherein the one or more additional foam layers are constructed of a different type of foam than the memory foam layer. 
     
     
         14 . A foam pillow, comprising:
 a first layer of foam possessing a top and a bottom surface; and   a second layer of foam possessing a top and a bottom surface, disposed so that the top surface of the second layer is in contact with the bottom surface of the first layer of foam, and possessing a pattern imprinted upon the top surface of the second layer.   
     
     
         15 . The foam pillow of  claim 14 , further comprising one or more additional foam layers disposed below the bottom surface of the second layer. 
     
     
         16 . The foam pillow of  claim 14 , wherein the pattern imprinted upon the top surface of the second layer of foam reduces the overall firmness of the pillow. 
     
     
         17 . The foam pillow of  claim 16 , wherein the first layer of foam possesses a pattern imprinted upon its bottom surface, the pattern reducing the overall firmness of the pillow and designed to complement the pattern imprinted upon the top surface of the second layer of foam. 
     
     
         18 . The foam pillow of  claim 14 , wherein the overall height of the combined first layer and second layer is roughly between four to six inches. 
     
     
         19 . The foam pillow of  claim 14 , wherein the pattern imprinted upon the top surface of the second layer of foam is comprised of concentric circles formed by alternating peaks and troughs. 
     
     
         20 . The foam pillow of  claim 14 , wherein the pattern imprinted upon the top surface of the second layer of foam is an egg crate pattern.
