A folding chair has a support frame with a back support portion, front leg portions, and rear legs. A seat is pivotally coupled to the support frame. A flexible back support is coupled to the support frame, and has a lumbar support member extending down from the back support to reach a lumbar region of a user's back. The lumbar support member extends from the back support into a space between the back support and seat. The seat pivots in a downward direction away from the back support and lumbar support ID member, so that the seat folds without interfering with the lumbar support member. The back support also has a perimeter flange disposed across the rigid back support perimeter, and free to move with respect to the rigid support frame in response to a load applied to the flexible back support. The perimeter flange extends across a gap created between the flexible back support and the support frame, such that when a load is applied to the back support and the back support flexes, causing the gap to open, the perimeter flange conceals the gap as the flexible back support goes from a loaded position to an unloaded position, thereby preventing pinching of articles of clothing or skin of a user.
