The seat shells are embedded in a frame construction. Makes a stable impression. The backrest can be adjusted perfectly using the lever. No problem finding a good sitting position.

The chair itself is decently comfortable, and I was initially satisfied. The chair itself is for my son who is 6'1" and he loves how the chair fits him. The headrest and curves in the back of the chair are built for someone his height. The armrests also adjust which is a bonus.

I spend 12–18 hours a day seated since I am on a computer for business and because I enjoy gaming in the evenings. I was pleasantly surprised by how good this chair was. All day long, you won't get tired of it because it's the perfect combination of firm and soft.
