Did you know the average person sits more than 9 hours per day? Want to be more productive and energetic during your day instead of being focused on your discomfort? BACKBONE CUSHION is a great way to help address your pain, posture, muscle weakness and poor seating. This patented, research-driven, doctor recommended back support is a cost-effective option to help reduce muscle stress and strain that you face daily in your car, office or plane. Save yourself from expensive chairs that don't fit, frequent doctor visits and even surgery. The BACKBONE Cushion can help to ease your pain and improve your comfort in any chair by encouraging your body's natural, postural alignment. Unlike some others on the market, The BACKBONE CUSHION was patented and designed by a physical therapist who has helped thousands of patients resolve their back pain and improve their quality of life. I sell this product because I was a former facilities manager who used to be the person responsible for supplying products like this to the staff. I personally love this and have one on my own chair. Works great for me. I like that I can adjust the straps to fit my office chair and it also fits my car for long trips. Quality products last and are used. If you get stiff shoulders you need this.
