*Note this product is designed firm, but has some give. We spend so much time hunched over a desk, computer and phone, that we need to take time to support extension and flexibility in our spine! The Ultimate Back Roller is everything you ever wanted in a back roller and more! FOR EVERYONE: This roller is designed to be used by everyone! Whether you are a yogi looking for the next generation yoga wheel; a runner; a mom/dad with back pain; an elite cross fitter or powerlifter; or just someone looking to support healthy spinal motion! SPINE GAP: When you roll your back on a basic flat roller, you are actually jamming the spinal segments and restricting motion as you roll- the exact opposite of what you are trying to achieve! Our revolutionary design was created to support natural spinal movement and enhance overall mobility. HOLDS 1000lbs: We created a roller that can support 1000lbs! That means you don't have to worry about it breaking under you! This roller is built from the highest quality tough molded foam in the world. HEIGHT / WIDTH: This roller is designed at 11 inches tall which is the perfect height to increase leverage and allow you to create extension. It is also stable at 7.5 inches wide. So it won't tip over when you are rolling. INVENTED BY A CHIROPRACTOR: our very own Dr. Sonia Pasquale created this Patent Pending Design! TRAVEL FRIENDLY: While this Roller is definitely a beast, it will easily fit in all backpacks and suitcases! It will be your new favorite travel buddy!
