I work a sedentary job, and this helps me sit up straighter and work my core as I sit for long hours everyday

I purchased this for work and I love it! I don't slouch in my chair and my back is no longer in pain!

It's only been a week and I can feel the difference already. My back is thanking me for this decision.

I work in an office and spend a lot of time sitting. I got this a couple of weeks ago and I LOVE it!!

I wish this was a little larger for my chair but, overall ii is a great product. It makes me sit up in my chair and has worked my abs.

My husband uses this disc while at work and says it's providing him so much more comfort and he can really feel his muscles engaging.

Easy to fill with air to fit your comfort needs. Fits most chairs and helps with posture and engaging your core.

I wanted to get a balance ball chair but thought would try the balance disk glad I did.,I love it!!!!

I like it.  I cannot have a complete ball to sit on at my desk, but this is good enough to keep me engage and active while I am sitting. 

Love the disc! Allows me to do my back exercises at work without bringing a full sized ball into my small office!
