The CPS Adjustable Piano Chair is 15 1/2 wide and 15 1/2 deep and weighs about 25 pounds. The height of the back support is about 34 above the ground. The seat of the piano chair has a padded leatherette top and can be adjusted instantly from the height of 17 to 22 with 7 positions by simply pressing two small blades together. It can be adjusted higher and much more easily and quickly than the adjustable studio piano bench. As an additional safety measure a latch can be pushed to lock in the position. The piano chair is made of solid hard wood with gloss finish and is available in ebony (black) color. This product carries a one-year limited warranty against defects in materials and workmanship.
