This a heavy-duty polystyrene chair, not a light plastic. It looks and feels heavy like wood. Great blue color. Really good manufacturing that made putting this chair together fast and easy. Well labeled screws, good visual instructions, better-than-typical-packaged-Allen wrench, and all the drill holes are aligned perfectly. The way you expect them to be for this kind of furniture. The cup holder can go on either arm and even pushes in under the arm, out of the way, if you like. This chair looks and feels heavy duty and sturdy. Built to last. Highly recommend.
