Steel frame construction. I would recommend this chair and buy it again.

The sturdy construction of the chair conveys a feeling of stability and durability. The high-quality material and precise workmanship are visible. The adjustable armrests allow me to adjust them to my ideal height, ensuring optimal support for my arms and wrists.

Impressed by the chair's quality. Above all I want to mention how nice the design is. I was doubting wether or not it would be worth it to get a design, as there's quite a premium on top of the base price, but a particular one stood out to me. Having purchased it, I do not regret a single cent. It's extremely well executed. I am really impressed by the effort that went into this. I am impressed by the quality of every part of the chair. It is a joy to use, it feels incredibly sturdy and comfortable, and with the amazing design. I think this chair is worth every cent that is asked. My only complaint is that the delivery service is impossible to deal with, as always.
