Linon Colton 13.5 in Task Chair with Adjustable Height & Has Arms, 300 lb. Capacity, Charcoal

[This review was collected as part of a promotion.] This chair was not hard to put together at all. The wheels come already attached to the base. You take the pole and connect it to the base just by inserting it into the center of base. Then attach the seat the pole and you are all set. I have kind of thick carpet and the wheels move find. The cushion of the seat is NOT removable. It supports your back while sitting. It does have the hydraulic adjuster to lower or raise the seat. Maximum weight is 275 pounds. The color is charcoal grey but to me it kind of looks brown at times (could be my eyes). The material is soft and smooth. I really like the chair!
