This is a comfortable chair. I like the pneumonic device. It works decently. It's a bit moveable, from the footstool up, but that allows for some back and forth motion while sitting in the stool. I'm not sure that's what they were after, but it works to my liking. The base is very solid. What I don't particularly like is the zipper down the back of the upholstery on the stool. In my opinion it makes it look less than professional. The leather/vinyl(?) is not the highest of quality, but I didn't pay top dollar either:) The upholstery quality is the reason for 4 stars instead of 5. The red color is a bright red. It was a tiny bit lighter and brighter than the pic, but otherwise the same hue. I put it together by myself in about a half hour. Overall I'm happy with my purchase.
