Abstract
A mattress can include one or more layers of foam material, an adjustable air layer including an air bladder, and a valve. The valve can be fluidically connected to the air bladder and configured to regulate pressure of the air bladder in response to actuation. Some embodiments can include a foam material positioned inside the air bladder.
Claims17
A mattress system comprising:
- a mattress comprising:
- a fabric cover;
- first and second layers of foam material positioned inside the fabric cover;
- an adjustable air layer positioned inside the fabric cover between the first and second layers of foam material, the adjustable air layer comprising:
- an air bladder;
- and
- an open-cell foam material positioned inside the air bladder and configured to bias the air bladder to an inflated position when the open-cell foam material is exposed to atmospheric pressure;
- and
- a valve system fluidically connected to the air bladder and configured to regulate the air bladder;
- the valve system comprising:
- a valve configured to selectively expose the open-cell foam material to atmospheric pressure, the valve comprising a solenoid and a solenoid controller coupled to the valve and configured to engage the valve;
- a pressure sensor;
- a processing unit;
- and
- a computer memory storing instructions that are executable by the processing unit;
- wherein at least some of the instructions, when executed by the processing unit, cause the processing unit to issue commands that:
- open the valve for a first period of time to establish a desired pressure;
- close the valve after the first period of time;
- wherein the mattress is configured to be folded upon itself in a shippable position to reduce a dimension of the mattress in at least one direction;
- and
- packaging configured to compress and retain the mattress such that each of the air bladder, the open-cell foam material, and one or more layers of foam material are compressed.

A mattress system comprising:
- a mattress comprising:
- one or more layers of foam material;
- an adjustable air layer positioned adjacent at least one of the one or more layers of foam material, the adjustable air layer comprising:
- an air bladder;
- and
- an open-cell foam material positioned inside the air bladder and configured to bias the air bladder to an inflated position when the open-cell foam material is exposed to atmospheric pressure;
- and
- a valve system fluidically connected to the air bladder and configured to regulate the air bladder;
- the valve system comprising:
- a valve configured to selectively expose the open-cell foam material to atmospheric pressure, the valve comprising a solenoid and a solenoid controller coupled to the valve and configured to engage the valve;
- a pressure sensor;
- a processing unit;
- and
- a computer memory storing instructions that are executable by the processing unit;
- wherein at least some of the instructions, when executed by the processing unit, cause the processing unit to issue commands that:
- open the valve for a first period of time to establish a desired pressure;
- close the valve after the first period of time;
- wherein the mattress is configured to be folded upon itself in a shippable position to reduce a dimension of the mattress in at least one direction;
- and
- packaging configured to compress and retain the mattress such that each of the air bladder, the open-cell foam material, and the one or more layers of foam material are compressed;
- wherein the mattress is folded with multiple hinges formed as elastic sections of material of a bottom surface of a cover of the mattress, the elastic sections have elastic properties that allow the elastic sections to stretch more than neighboring sections of the cover.

- a pressure sensor;
- a processing unit;
- and
- a computer memory storing instructions that are executable by the processing unit;
- wherein at least some of the instructions, when executed by the processing unit, cause the processing unit to issue commands that:
- open the valve for a first period of time in response to a detection of no user present on the mattress;
- close the valve after the first period of time.
