Abstract
A wheelchair is provided. First supports for supporting a user of the wheelchair are unevenly disposed to form a perimeter, and second supports for supporting the user of the wheelchair are unevenly disposed at least partially within the perimeter of the first supports. The first supports support the user when the first supports are in a raised position and the second supports are in a lowered position. The second supports support the user when the second supports are in a raised position and the first supports are in a lowered position. A alternation of supporting the user with the first supports or the second supports facilitates reduction of pressure sores of the user. In various embodiments, multiple groups of supports are used, the supports contour to a user's anatomy and/or the supports are pneumatic.
