A Solution... It's that simple... The Wonder-Roll: Software for your Back!How can using the Wonder-Roll help relieve my back pain, and prevent future back problems? Over 70% of the United States population experiences back pain during their lifetime and most have experienced back pain within the last 3 weeks; this is why the Wonder-Roll was invented.The majority of people think sitting is a restful position, but clinical research has shown that sitting creates increased pressure in the discs of the lower spine. The problem is made worse by slouching in our chairs, which most people tend to do. The majority of chairs produced lack adequate lumbar support which can contribute to slouching. Prolonged and repetitious slouching can increase strain in the lower back causing damage or injury to spinal discs. The Wonder-Roll prevents slouching by supporting the natural curve of the lower back when sitting. Lower back support when sitting also encourages forward tilting of the pelvis area. When supported correctly by the Wonder-Roll the discs and joints of the lower spine are aligned in a position which mechanically is less stressful, and can help prevent future injury and pain.
