Ergo Sit, silver

This product is basically a slice of a yoga ball that your can put on a chair. You get the stability of the chair and the freedom for your pelvis to move like a yoga ball. Great for long stretches at the computer or at conferences and workshops.Ergo Sit, silver

When i use my ergo sit I can feel myself working needed muscles that help me sit up more straight

Unfortunately, it made my back pain worse. However their customer service was great, and they're allowing me to return it. My chiro loves hers; maybe you'll have better luck than me!

Uncomfortable after a short period of time. The rubber is very thick, so it doesn't give the feel of an exercise ball.

I LOVE IT! Now instead of bending my neck & shoulders forward to read the computer screen my whole body just rocks forward and I don't have to go to the massage therapist so often! It's already paid for itself!

Works as stated, helps me to remember about my posture. Comfortable for sitting on all day.

Seemed like a better idea than what it is in reality. Not bad, but I've found better back support options.

I got one for work desk, one for home desk.... I love it!!!
