Mattress with a cavity and airway channel

Abstract

A mattress comprises one or more cavities disposed within the mattress. A filter assembly is removably mounted within the cavity at a first distance from the mattress' upper surface. One or more channels are disposed laterally within the mattress and connect the cavity to the mattress sidewall so that intake air is allowed in and exhaust air can escape. In one version an aroma assembly is also removably mounted within the cavity. Within the channels there may be disposed one-way valves to allow air to flow only in a first direction or a second opposite direction so that exhaust air is not mixed with intake air. A fitted sheet used in combination with the mattress may include a sleeve corresponding in size and location to the cavity, where the sleeve is made from an odorless washable material. The sleeve may be retained within the cavity by a plastic ring.

1 . A mattress comprising:
 a mattress body having a first surface and a second surface substantially parallel to each other and connected by substantially perpendicular sidewalls;   a cavity disposed within the mattress body and extending from the first surface toward the second surface;   a first aperture defined where the cavity intersects the first surface;   a filter assembly removably mounted in the cavity transverse to the extent of the cavity at a first distance from the first surface; and   a first channel disposed laterally within the mattress, wherein the first channel has a distal end and a proximal end, said distal end being connected to a first opening in the cavity at a second distance from the first surface which is greater than the first distance, and the proximal end being connected to an opening in the sidewall of the mattress.   
   
   
       2 . The mattress according to  claim 1 , wherein an aroma assembly is removably mounted within the cavity at a third distance from the first surface which is greater than the second distance. 
   
   
       3 . The mattress according to  claim 1 , wherein the cavity extends completely from the first surface to the second surface and the mattress is reversible, and further comprises:
 a second aperture defined where the cavity intersects the second surface; and   wherein the filter assembly is removably mounted transverse to the cavity at the third distance, and the aroma assembly is removably mounted within the cavity at the first distance.   
   
   
       4 . The mattress according to  claim 1 , further comprising: at least a second channel, having a distal and a proximal end, disposed laterally within the mattress, said second channel distal end being connected to a second opening in the cavity at a distance between the first distance and the third distance, and the second channel proximal end being connected to the a second opening in the mattress sidewall;
 a first valve disposed within the first channel and configured to allow air to flow in a first direction; and   a second valve disposed within the second channel and configured to allow air to flow in a second direction, wherein the first direction and the second directions are opposing directions.   
   
   
       5 . The mattress according to  claim 1 , further comprising:
 a second cavity disposed within the mattress body;   a respective channel disposed within the mattress body, the respective channel having a distal end connected to the second cavity and a proximal end connected to the sidewall; and   the second cavity having disposed therein a respective filter assembly.   
   
   
       5 . The mattress according to  claim 4 , further comprising a respective aroma assembly in said second cavity. 
   
   
       6 . The mattress according to  claim 4 , further comprising:
 additional respective channels connected to the second cavity; and   single respective valves disposed within each of the respective channels, wherein each respective valve is configured to allow air to flow only in one of the first direction and the second direction.   
   
   
       7 . The mattress according to  claim 1 , wherein an area adjacent the first aperture and a portion of the cavity abutting the first aperture are lined with an odorless, washable removable material. 
   
   
       8 . The mattress according to  claim 1 , wherein the cavity has an oval cross-sectional shape transverse to the extent of the cavity. 
   
   
       9 . The mattress according to  claim 1 , wherein the channel is formed from flexible, odorless material. 
   
   
       10 . The mattress according to  claim 5 , wherein an insertable plug is disposed within one of the first aperture and the second aperture. 
   
   
       11 . The mattress according to  claim 1 , wherein the mattress body is an inflatable air mattress. 
   
   
       12 . In combination with the mattress of  claim 1 , a fitted sheet comprising:
 a sleeve corresponding in size and location to the cavity, the sleeve being made of an odorless washable material; and   a plastic ring insertable within the sleeve to retain the sleeve within the cavity.
