Your body weight flattens your gluteus muscles. Even with corrected posture, your gluteus muscles will flatten under your body weight. Since the ligaments that connect your gluteus muscles to your back muscles require equal tension on both sides, your back muscles must tighten to equalize the tension. This tightening creates new pain causing stresses in your back.

I know of only one patented Orthotic Cradling System that can cup the gluteus muscles and stop them from flattening, effectively stopping the automatic tightening of your back’s muscles when you sit. This avoids pain and strain, and keeps more stress off your back’s muscles, joints, and ligaments.

3. It needs to cradle the pelvis and float your spine:

The lower pelvis spreads apart, and the upper pelvis pinches together, putting increased pressure on the the lumbar-sacral joint and ligaments. Like a pain relieving shock absorber, BackJoy lifts your pelvis up off the sitting surface so you sit as much as 3 inches taller. Your pelvis will float in a natural and protective cradle of muscle tissue.

Few cushions restrict the spreading of the lower pelvis reducing pressure on the lumbar-sacral spine. The six components of the pelvis can work fluidly as one unit, minimizing the wear and tear on the sacral joints.
