US Jaclean Stretch Mate orthopedic back stretcher for improving posture, increasing flexibility, and relieving pain. Experience a muscle-relaxing stretch for relief from back pain. Back pain is very often caused by poor posture. Hunching forward to perform everyday tasks forces the spine into an abnormal position for long periods of time. This wears and tears muscles that support the spine, leaving you with constant aches and stiffness. Reverse this trend before it's too late. The Stretch Mate is shaped according to the spine's natural curves to offer support and ease muscular fatigue. Its sturdy, lightweight design allows you to take it with you everywhere.
