The 18" wide, 16" deep seat has 2.5" of durable molded polyurethane foam cushioning covered with easily cleaned vinyl.

Like the color. Perfect height but the “adjustable” ring is not so adjustable and very hard to get on let alone move. Also, the back of the back rest is black and from the image it looked chrome so a little disappointed there. As you can see, next to my white table, it’s actually a bit off-white. Other than that, it’s good!. Taylin. Taunton, MA. Thu, 28 Feb 2019

Chair looks great. The arms rotate which was cool at first but i ended up drilling them together to stop it because it got annoying quickly. Would prefer a secure armrest.
