Works great on my Formula racer chair purchased in 2016 (almost 7 years ago). Also purchased on a Friday morning, delivered on Monday.

This is a perfect chair for my son, for his desk/gaming needs. While assembling it, although relatively straightforward, one of the castors wouldn't fit! After a half hour of trying to bang it into place, it finally went in far enough to be safe to sit on. Overall, it's a great-looking chair!

This chair is absolutely comfortable to sit on. It's soft, the armrests are height adjustable which I can't confirm myself as I haven't tried it, but I'd like to point it out anyway) and the material always goes back to its original position. The cushion provides very good support when sitting and helps you sit up straight, which is comfortable for your back. The neck pillow is also very comfortable. The seat cushion itself is made of leather and looks very elegant.
