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).

I agree with the 5-star reviews. High-quality chair. The heavyweight alone and the large size of the box make a good impression. Quick and easy to assemble. Very smooth-running castors. Everything is adjustable.

Very comfortable and sturdy chair! It was pretty straightforward to put together, instructions were easy to understand. Got this for my home office for work, and I can sit for long periods of time without needing to shift or get up due to soreness. Would highly recommend for gaming and work!
