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.

As a someone who spends extended periods at a computer, I sought a premium chair that would focus comfort, support, and function, while simultaneously allowing me to play guitar from the same piece of furniture. This chair exceeded my expectations in every aspect. The chair's adjustability options are impressive. The height can be easily adjusted, as can the pitch of the backrest. The armrests are also adjustable.

The best chair. My son uses it to study for several hours per day. Love it!
