I decided to try this out for my office chair and it's absolutely the best I have ever had. I spent hundred of dollars on office chairs from office supply stores and have always been very dissatisfied with the quality. I have a bad back and in a couple of weeks, I would be sitting on wood or metal. I thought I would try this massage chair out and it's FABULOUS! If you want a good firm seat, this is the chair for you. I LOVE IT - and wouldn't trade it for any other.
