The general design for a lumbar support belt resembles a girdle that fastens in the front. Typically, the belt will feature a combination of Velcro and buckles on the front, making it possible to adjust the device to a comfortable fit while still providing support. Along the lumbar area of the lower back, the belt normally is designed with extra padding to cushion the area as well as provide back support. Many designs include a non-roll pattern that helps to keep the lumbar belt in place even during strenuous activity.
