BackJoy is not a simple cushion or support device. When you sit on BackJoy, you activate the patented Orthotic Cradling System. BackJoy "turns-on" under your body weight and works in unison with your body.
This system provides dynamic support by rotating your pelvis from three points simultaneously - the Ischia, Sacrum and Ilium. BackJoy cups, cradles, and floats your pelvis in your muscle and soft tissues, so your lumbar spine can find its most comfortable position while you sit instead of becoming locked in a fixed position. Unnatural pressures and strains are reduced - your pelvis is free!
The Relief differs from the Posture Plus in that it is made of neoprene, works the core less and is for people who want to improve their posture but have existing back issues.
