Don't Let Sitting Ruin Your Back

Dr. Elizabeth Leeds, Pelvic Floor and Orthopedic Specialist, explains the benefits of Core-Tex Sit.

I really like this Core-Tex Sit. I wake up with back pain and tightness every morning and sitting on this and doing some movements helps me feel much better and loosens me up.

Great product!

The Core-Tex sit is the perfect tool to use with patients that have problems with weak core muscles and impaired ability to maintaining sitting balance. Great tool and I’ll be looking to purchase the bigger version soon!
