The chair description indicates that it can be raised to 21 inches; it only goes to 19 inches. The description also states that the chair top rotates. It does not rotate with any weight on top of it, which defeats this feature. I am returning this product. I'm very disappointed with the time I wasted trying to return this product to the Walmart store only to find out I have to returned it directly to the supplier. I contacted the supplier via email, and they wanted to give me a 20% discount for their misrepresentation, if I chose to keep the chair.
