“As a programmer, I sit in this chair for over 10 hours a day. The S9 is designed so that I don’t feel tired even after long periods, and it provides excellent support for my lower back and spine. Assembly was also quick, and overall, I’m very satisfied.”

Much Better Than My Old Chair

“I’ve been using the S9 chair for about two weeks now. Honestly, it’s pretty comfortable, especially the lumbar support — my lower back feels a lot better after long work sessions. The fabric feels nice, which is great.
