Abstract
Described herein are mattresses with localized air chamber support. A mattress can include a first air chamber positioned at a shoulder region, a second air chamber positioned at a hip region and fluidly connected to the first air chamber, and a foam insert positioned between the air chambers. The air chambers can share a common internal pressure. Decreasing the common internal pressure in the air chambers can cause the foam insert to increase support at a lumbar region of the mattress. Additional foam inserts can be positioned between at least one of the first air chamber and a head end of the mattress, the first and second air chambers, and the second air chamber and a foot end of the mattress. The mattress can also include a foam rail structure that extends around a perimeter of the mattress to surround the components therein.
