## Abstract

A breathable mattress including a plurality of layers, where one of the mattress layers is further comprised of a plurality of sections and the sections are comprised of different types of materials, which have varying firmnesses and feel, and where each of the layers is comprised of material that is perforated or of an open-cell structure to allow for air circulation. The mattress is supported by an air filtration foundation capable of creating an air flow within the mattress.

## Claims

### Claim 1

A mattress, comprising:
a plurality of layers, each layer extending in a substantially parallel, horizontal direction and being positioned in vertical relation to other layers and each layer further having a perforated or open-cell structure;
at least one layer being comprised of material selected from the group consisting of convoluted latex, regular latex, viscoelastic polyurethane, regular polyurethane or convoluted polyurethane; and
an air filtration foundation coupled to the mattress, the air filtration foundation including a fan assembly that displaces air through each of the plurality of layers.

### Claim 2 (depends on 1)

The mattress according to claim 1, wherein the plurality of layers include a comfort layer, a contour layer, an air foam layer and a foam base layer.

### Claim 3 (depends on 1)

The mattress according to claim 1, wherein the air displaced by the fan assembly is heated.

### Claim 4 (depends on 1)

The mattress according to claim 1, wherein the air displaced by the fan assembly is cooled.

### Claim 5 (depends on 1)

The mattress of claim 1, wherein the fan assembly displaces air of varying temperatures.

### Claim 6

A mattress, comprising:
a plurality of layers, each layer extending in a substantially parallel, horizontal direction and being positioned in vertical relation to other layers and each layer further having a perforated or open-cell structure;
at least one layer being comprised of material selected from the group consisting of convoluted latex, regular latex, viscoelastic polyurethane, regular polyurethane or convoluted polyurethane; and
an air filtration foundation coupled to the mattress, the air filtration foundation includes a fan assembly and a filter assembly, wherein the fan assembly displaces air through the perforated or open-cell structure; and
wherein the filter assembly includes a filter that is selected from the group consisting of HEPA, HEGA, carbon, carbon-zeolite, ionic, ozone, or ultra-violet filters.

### Claim 7 (depends on 6)

The mattress according to claim 6, wherein the temperature of the air displaced by the fan assembly is selected by the user.

### Claim 8 (depends on 6)

The mattress according to claim 6, wherein the air displaced by the fan assembly is heated.

### Claim 9 (depends on 6)

The mattress according to claim 6, wherein the air displaced by the fan assembly is cooled.
