Proactive Disc
I have used the Proactive Disc for several years. I first started using it when I had three hierniated discs and a friend suggested that I try it. I really believe that it was instrumental in my healing. For sometime I took one with me everywhere I went. I use one in the car and when I find the seating uncomfortable. I always take one when traveling.

Perfect Posture
Recuperating from a bruised tailbone with simultaneous sciatica, I was looking for something that could provide some cushioning yet I didn't need something as thick as a coccyx cushion. What sold me on ProActive disk was the fact that it was compact and lightweight. I was also quite interested in the thermarest technology as I love my thermarest mattress and I hoped this cushion would measure up quality wise. I am travelling overseas and wanted something compact and lightweight that would protect my coccyx. I have been sitting on this cushion for a good month now and I have noticed that my posture is erect and I no longer catch myself slouching with my shoulders hunched forward. I've already recommended it to a few co-workers.

My husband bought me my first one after I had lower back surgery in 2005. It simulated the big ball that I also used but this was portable for me. The price has not changed at my surprise. Using this especially when sitting for long periods of time made a huge difference and aided in my recovery from the surgery. My back felt stronger and it helped my core with posture and strength. I love this.

Proactive disc
Because I do a lot of sitting and have shoulder issues the proactive disc helps me to sit properly without hunching over. The fact that you can adjust the amount you inflate it is a bonus.

Helps me sit in so many places.
I love this disc so much, I had lumbar surgery 6 months ago and I take it to restaurants and music events. I find my husband keeps borrowing it, so I just ordered one for him. Very happy with this product.

My Whoopie Cushion is Great!
My colleagues affectionately refer to my disc as my 'whoopie cushion' and now I do too. It's a great way for me to be more conscious of my posture and therefore more comfy throughout the day. I bought one for my hubby for father's day and he really likes his too. I have not hesitated to refer my colleagues who've asked.

LOVE it!
I just purchased my second disc so I could have one at home and at my office. I have low back issues and this item is the PERFECT cushion to have if you sit for hours at a time. I bought my first one several years ago and it is still in perfect condition!

I have an older model that I have used for many years, very satisfied. This newer model has a stiffer nozzle that is hard to adjust with one hand. Also I would have appreciated some special instructions with the disc for first time use since it takes a long time to inflate (24 hours). I called Fitterfirst and they explained so that service was great. Still satisfied with this version and have recommended it to numerous friends.
