Customer Reviews

Makes me tired - but in a good way.
I bought this to use on my desk chair to improve my posture and make working at my desk less sedentary. Because you have to subtly but constantly work at maintaining your position your muscles will definitely feel it until you get used to it. All in all I'm very happy with it and it was worth the price just for the laughs the first time I sat on it!

great for sitting
I bought this for my 87 year old mother who has neurolagia in her legs. She has found this to be the most comfortable seat for any kind of sitting. No pressue on the backs of her legs and because she can control the firmness of the cushion she has no pressure on her lower spine. Great product for her needs!

Great for core
I bought this to sit on at work. I was hoping that it would help my posture (I have a tendency to slump) and strengthen my core to help address some lower back problems.

After a month of use, I love it and have recommended it to several people--including people at work who want to know what the heck I'm sitting on.

As I hoped, it basically demands good posture. Also, my abs are definitely getting stronger. I could feel it working about 20 minutes into the first time I sat on it. And today I noticed in the mirror that my upper abs definitely have more definition.

Great for anyone who wants a core strengthening exercise they don't have to think about and that doesn't add any time to your day.
