Claim 10:
11. 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.
