ABSTRACT:
A foldable chair is disclosed herein. The chair is made from a plurality of back, seat and intermediate members. The back members are joined along the top. The seat members are joined along the front. The other end of the back and seat members are joined to opposite ends of the intermediate members to from hinged joints that allow the chair to be folded and unfolded. Leg members extend from at least two of the back members and at least one of the seat members. The inner seat width of the chair is approximately equal to the length of the back of the chair. The members not functioning as leg members are sized to minimize the outward force on the joints during opening and closing of the chair. Tip prevention members, adjustment techniques and a headrest are also disclosed.
