Assembly is simple and easy to follow thanks to the included instructions. Just follow the step-by-step instructions and you won't have any further problems. You may need a second person to put it on what I call the height adjuster.

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.

All the pieces and parts were packaged with care. Everything went together perfectly. The chair has great adjustable lumbar support and it's so comfortable. I use this chair approximately 8 to 10 hours a day with no issues. It's been about 2 weeks now since I ordered the chair. So far, its amazing. This is a great chair and in my opinion it's definitely worth the price.
