I'm not sure the date of this stool but this piano stool has been in my family for a LONG TIME! The stool was repaired long ago (broke a leg) and was originally a four claw feet stool but it is just a three claw feet stool now. When the stool seat is all the way down, the total height measurement of the stool is 18.5 inches. Fully chair erected, height is approx 25 inches.
