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 mahogany color. This product carries a one-year limited warranty against defects in materials and workmanship.
