This is an office chair made with very good quality material, white color chair with back seat cushion, black color seat cushion is harder to get dirty! Installation is sample and easy, no additional tools are needed, because it is fully equipped, of course, it takes some effort to press the wheels on it. It look me less that 20 minutes to complete the installation by myself. The armrest can be pulled up and down, an the armrest can be pulled up when the  chair is not used. The chair can be put into the table without taking up space. Wayfair shipped quickly and received the item in less that 5 days! Overall, I think this office chair is very good, I like it! I’ll recommend to my friends!
