The office chair is larger than other chairs, and it could accommodate different body build. The ergonomic chair provides 4 supporting points(head/ back/ hips/ hands) and a proper lumbar support. It's easy to adjust seat height, headrest, backrest and flip-up arms to meet different needs, good for sitting long hours. The recline function makes you tilt the backrest back (90~125°) or sit straight freely. Folding the armrests up 45°, you can push the executive office chairs directly under the desk to save valuable space. | Cloudrest Pro | | Big and Tall Ergonomic Mesh Office Chair Wide Cushion Executive Chair High Back Reclining Computer Chair Task Chair | Black | Best Buy
