Hybrid mattress unit

Abstract

An innerspring unit with a plurality of helical coils arranged in at least one array in which the coils are generally aligned in rows, with the coils having generally cylindrical bodies formed by helical turns of the spring with openings in between each of the helical turns. The embodiment may also include a plurality of compressible support members, each of which is secured within at least one of the openings so that each one of the compressible support members is secured within an opening. The compressible support members may be stacked on top of one another. A plurality of innerspring units may be arranged together to form a mattress.

What is claimed is: 
     
         1 . A mattress having a top and bottom, comprising:
 a plurality of springs with longitudinal axes, and each spring within said plurality exhibiting a number of coils, such that a space in between two coils defines an opening, said springs arranged in a direction such that said longitudinal axes are perpendicular to said top and said bottom of said mattress;   a plurality of foam strips, each strip having two elongate sides and a thickness, said strips arranged such that at least one side of each strip is secured within an opening defined by two coils of a spring.   
     
     
         2 . The mattress of  claim 1  wherein said plurality of foam strips includes at least two different thicknesses. 
     
     
         3 . The mattress of  claim 1  wherein said thickness is between 1 inch and 1.5 inches. 
     
     
         4 . The mattress of  claim 1  wherein said plurality of foam strips includes foam strips of at least two different densities. 
     
     
         5 . The mattress of  claim 4  wherein the density is between 18 and 55 IFD. 
     
     
         6 . An innerspring unit for a mattress, comprising:
 a plurality of springs arranged in a row, the body of each spring being generally cylindrical, having at least two coils, and having a longitudinal axis;   a plurality of resilient elements each having a height dimension, a width dimension, and a length dimension, arranged such that the length dimension of said plurality of resilient elements is secured between two coils of said springs, whereby the height dimension fits between said two coils.   
     
     
         7 . The innerspring unit of  claim 6 , wherein a plurality of units are arranged to form a mattress. 
     
     
         8 . The innerspring unit of  claim 6 , wherein a resilient element is secured within each coil of each spring, thereby forming a stack of resilient elements secured in such a stack by said coil. 
     
     
         9 . The innerspring unit of  claim 8 , wherein said stack generally has a top side and a bottom side, and a resilient element adjacent the top side has a shorter height dimension than a resilient element adjacent the bottom of side of the stack. 
     
     
         10 . The innerspring unit of  claim 6  wherein said height dimension is between 1 inch and 1.5 inches. 
     
     
         11 . The innerspring unit of  claim 6  wherein each of said resilient elements has a density between 18 and 55 IFD. 
     
     
         12 . The innerspring unit of  claim 6  wherein said plurality of resilient elements includes at least two different height dimensions. 
     
     
         13 . The mattress innerspring of  claim 12  wherein said height dimension is between 1 inch and 1.5 inches. 
     
     
         14 . A mattress innerspring comprising:
 a plurality of helical coils arranged in an array in which the coils are generally aligned in rows, each of the coils having a generally cylindrical coil body formed by helical turns of the spring with openings between each of the helical turns, having a longitudinal axis;   a plurality of compressible support members, each of which is secured within at least one of said openings, said compressible support members are stacked in the direction of said longitudinal axis; and   wherein said plurality of the coils and the compressible support members are arranged together to accommodate a user-selected seize of a mattress.   
     
     
         15 . The mattress innerspring of  claim 14  wherein said plurality of compressible support members includes at least two different thicknesses. 
     
     
         16 . The mattress innerspring of  claim 15  wherein said thickness is between 1 inch and 1.5 inches. 
     
     
         17 . The mattress innerspring of  claim 14  wherein said plurality of compressible support members includes compressible support members of at least two different densities. 
     
     
         18 . The mattress innerspring of  claim 17  wherein each of said compressible support members has a density between 18 and 55 IFD. 
     
     
         19 . The mattress innerspring of  claim 14 , wherein said stack of compressible support members generally has a top side and a bottom side, and a compressible support member adjacent the top side has a shorter height dimension than a compressible support member adjacent the bottom of side of the stack.
