Patent Images
1. A surface configured to support a person in at least a horizontal position, comprising:
- a first section comprising laterally-spaced vertically-oriented inflatable bladders, at least one layer of an air permeable three-dimensional material, and a moisture/vapor permeable material, anda second section comprising laterally-spaced vertically-oriented inflatable bladders, the second section being longitudinally spaced from the first section, the second section comprising at least one layer of an air permeable three-dimensional material and a moisture/vapor permeable material,wherein the bladders of the first and second sections each comprise a bottom end, a vertical portion extending upwardly from the bottom end and a top end supported substantially by the vertical portion, and the bladders are supported at only the bottom end, and the bladders are spaced from one another by an unfilled region, and all of the bladders in each section have substantially the same height, and a portion of one of the first and second sections has a height that is shorter than the height of the other of the first and second sections.
