It was very easy to assemble and took me 20 minutes. You can do it on your own, but it's quicker and easier with two people (the backrest weighs quite a bit and the other individual parts aren't exactly light either).

Thank You DXRacer for still selling parts for a Chair I bought over 10 years ago Great experience fast shipping so I can fix my chair.

I like the chair, however, having a separate cushion for the lumbar support doesn't really work well. It fell over every time I got up. There should be lumbar support built into the back of the chair. I also had to add an ergonomic seat cushion because the seat was very hard. This solved the issue of the lumbar support falling down when I got up because I tucked it behind the seat cushion to hold it in place, but the lumbar support at that low height resting directly on the chair is way too low for a proper lumbar support. It would be well worth paying more for a chair with the lumbar support in the chair and a much softer seat cushion. I like the way the rest of the chair functions, such as the arm rests and way the sides of the chair wrap around.
