This chair is easy to install, the hexagon key is very long which is the best accessory tools among all the furnitures I bought before. I bought this chair because the back of it is white when I’m tired of full black chairs. And surprisingly the quality is so good. The chair has super thick padding, the foot rest is padded as well. Pulling it out and putting it back in is just a smooth process. Taking a short nap on it is super comfy. The headrest is also adjustable, works great for people of 5’2”. Highly recommended
