This chair is exactly what I needed. It provides support in my lower back. Has armrests that move front to back and up and down. They also turn in and out. This is very convenient. Head rest is adjustable. You can lay back in the chair and relax. Very comfortable. Was easy to put together. Adjustable height as well. I got this to help with Sciatic pain and sitting in an office chair all day for work. Pain has gone away.
