Hello Tony, Sorry to hear your mom is having back troubles. We are expecting the redeveloped large body wraps to be available around September time. However in the meantime we do recommend the Back/Hip Wrap. They are versatile, can be placed anywhere around the back, hip, or even arm or leg if required. Our 30 day return policy won't allow you to have an exchange for the large body wrap unfortunately. If you have any other questions please don't hesitate to ask. We wish your mum well with her recovery. Kind regards, Helen
