What People Say About The Spinery® Ergonomic Seat Cushion


“I have two sizes, one for regular chairs when I’m working at my desk and the other for my car. The first time I used it I instantly felt my core engage. It has made such a difference to the quality of time i spend sitting. And sorted out all my issues with my lower back. It’s such a simple idea, in one word – genius.”

“I received the foundation three weeks ago. I use it in my office all the time and feel it makes a big difference to my work station posture. I also like the fact that it comfortable, neat and easy to carry with me to meetings within the company. The color also makes it discreet and blends in very well.”

“Absolutely loving my foundation. I find it particularly useful for long car journeys. Gone are the days of dreading the drive for family day trips or journeys down the country. Its been a life saver for me or to be more exact a back saver!!”

Niamh Gleeson


“I love my new foundation. I think I would have stayed a sceptic if I hadn’t experienced the shift in the spinery offices for myself. Straight away my posture was so much better and everything just felt stronger and more engaged. Now I have one in work, one at home and my daughter takes hers to school with her. I’ll continue to recommend the spinery to friends and family and anyone else who will listen! Great people too.”
