“I have been sitting on a big square eggshell cushion at work for 10 years. It slips all over the place and I think I've done more damage to my back trying to keep it in position! Time for a new one. I was dubious but finally took the plunge when I saw how it was shaped for an office chair. I have had it in place for 2 weeks now, and it has improved my quality of life considerably. I no longer dread going to work because of the pain I will be in by the end of the day.”
