Seat size: Round seat (330mm diameter) Height adjustment: Approximately 460-650mm New suggested retail price: ¥22,000 (tax included) The seat cannot be raised or lowered by turning due to wear on the screw mechanism. *Adjustment is done by screws. (Images 7 & 8) One screw on the underside of the seat is not original. (Image 11) There are scratches, dirt, and rust on the metal parts due to use, but this does not affect functionality.
