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

I have been looking for a great office chair that was more than the standard desk chair and I came across Dxracer. They had a gamer's chair, designed for long hours sitting and playing. The chair looked fantastic with thoughtful additions to enhance the experience if sitting for long periods. This chair was good enough to sleep in! If you want an outstanding chair that you sit in for hours at a time, this is the chair to buy.

The chair looks great and is very comfortable. The chair is firm and I have had it for like maybe two weeks with using it as my work chair and gaming chair and I have no complaints for it.
