Lying Down Lying Down Use a firm mattress that gives good back support. To apply the least stress to your spine, lie on your side or your back while sleeping, rather than your stomach. When on your side, keep legs bent slightly, with top leg straighter at the hip.
Some people use a pillow between the knees for added comfort.
Keep chin in rather than jutting it forward. When lying on your back, keep legs straight. If you cannot tolerate this position, use a small pillow under the knees. The pillow under your head should raise your head to about the same level as your body. When on your side, your pillow should high enough to keep your head from tilting down, but not so high that it tilts upward.
