Abstract
Disclosed is a folding chair comprising a frame and a seat sheet, which has means for protecting a user's vertebral column and means for expanding the seat to improve its seating comfort and stability. The expanding means are connected to both sides of the seat, and the protecting means is coupled at its opposite ends to armrests, upper portions of frame elements or the expanding means. The expanding means are hanged on projections formed by bending upper portions of the front frame elements. The protecting means is held at a certain height on a back rest of the chair but being allowed to be laterally moved by holding means, thereby enabling length of the protecting means to be adjusted. The folding chair may have one or more means for protecting a user's vertebral column.
