Abstract
A bedding or seating product comprises a first layer of foam having a patterned first surface nested with a patterned surface of a second layer of foam to create a transition zone between the first and second layers of foam. At least one of the layers of foam may have additives therein. Each patterned surface comprises rounded peaks and rounded valleys. Air channels are created in the transition zone if the rounded peaks and rounded valleys of one layer of foam are a different height than the rounded peaks and rounded valleys of the other layer of foam.
Claims20
A bedding or seating product comprising:
- a pocketed spring core;
- a first piece of foam having a flat surface proximate the pocketed spring core and rounded peaks and rounded valleys on the opposite side from the flat surface;
- and
- a second piece of foam having rounded peaks and rounded valleys nested with the rounded peaks and rounded valleys of the first piece of foam, wherein the rounded peaks and valleys of one of the pieces of foam are smaller than the rounded peaks and valleys of the other of the pieces of foam such that air gaps extend through the product providing increased air flow through the product.
A bedding or seating product comprising:
- a core;
- a first piece of foam having a flat surface proximate the pocketed spring core and rounded peaks and rounded valleys on the opposite side from the flat surface, the rounded peaks and rounded valleys extending in a wave shape;
- and
- a second piece of foam having rounded peaks and rounded valleys nested with the rounded peaks and rounded valleys of the first piece of foam, wherein the rounded peaks and valleys of one of the pieces of foam are smaller than the rounded peaks and valleys of the other of the pieces of foam such that air gaps extend through the product providing increased air flow through the product.
A bedding or seating product comprising:
- a first piece of foam having a flat surface and rounded peaks and rounded valleys on the opposite side from the flat surface, each of the rounded peaks and rounded valleys of the first piece of foam having a zig-zag shape;
- and
- a second piece of foam having rounded peaks and rounded valleys nested with the rounded peaks and rounded valleys of the first piece of foam, each of the rounded peaks and rounded valleys of the second piece of foam having a zig-zag shape,
- wherein the rounded peaks and valleys of one of the pieces of foam have a height different than the rounded peaks and valleys of the other of the pieces of foam such that air gaps extend through the product providing increased air flow through the product.
