I’m happy with it. I don’t find myself sitting on it in as many different positions as I thought I would. In fact, I almost exclusively sit on it the traditional way but I like the fact that I can be comfortable on the chair at different heights due to the saddle style seat. I haven’t had any issues with back pain since I got the chair and I’m sitting on it for over 8 hours most days. After 1 month, I couldn’t tell you whether it has significantly improved my posture but I do think it has done a good job so far in making me more aware when I’m not sitting correctly.
