My husband has had back problems for quite a while now, mind you, he is only like 20. He's been sitting on chairs without lumbar support for a while now and I think it took its toll. This chair comes with the support he needs and his back doesn't hurt anymore. He sits on there all day long and trades stock while playing Runescape now. Lol! This was super easy to assemble, you don't need any tools at all because it comes with it already. It takes a bit of elbow grease to put everything together, but it's super easy. The instructions aren't clear, because it's just in pictures, but with a bit of matching items to the pictures, you can figure it out.
