ABSTRACT:
A layable seat includes front and rear paired supporting legs which are layably raised on a floor at two positions separated from each other in a back-and-forth direction, a seat member pivotably connected to the front paired legs, paired link levers each of which has one end pivotably connected to the corresponding one pivotal center of the seat member and the other end pivotably connected to the corresponding rear leg. The seat member is elastically held at its half-folded position by torsion coil springs, and has paired engaging pins which project sideward therefrom and engage the lower edges of the link levers to hold the seat member at its horizontal position against a user's weight.
