Keeping your spine in proper alignment is an important key to relieving back pain. The DMI Relax-a-Bac provides the ideal lumbar support to ease lower back pain. There are five lumbar vertebrae located in the lower back. These vertebrae receive the most stress and are the weight-bearing portion of the back. All the more reason to properly support this crucial and highly sensitive-to-injury area. The orthopedic design of the Relax-a-Bac helps to relieve tension and keep the spine in proper alignment, reducing stress and strain on this region. Chiropractors and physical therapists recommend lumbar support cushions to help maintain good posture while at home, in the office or on the road.
