Heals Off the End of the Bed

I recommend sleeping with legs elevated while undergoing treatment for low back pain. It decreases the pressure on the nerve roots and joint spaces in the back of the spinal column and drains the excess fluid, plus it relaxes the muscles in the front of the spine.

Move down a bit so the heals drop-off the end of the mattress. This prevents the back of the knees from out-stretching and the legs from rotating outward. The back of the end of the calves contact the sleep surface and provide for a more comfort sleeping posture.
