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).

The chair is highly adaptable for adapting to various body shapes, allowing for adjustments to both the armrests and the backrest.

Very comfortable chair overall, been using it for the past month now and can say being able to recline is an absolute game changer. One small thing i have to complain about with this chair specifically is that the armrests are a little dense and uncomfortable, but you can move them in multiple directions giving you the best chance of being the most comfortable. Overall i would give this chair a 9/10
