Sleeping on a hard bed and lying on your back is good for your neck and back. Avoid sleeping on your stomach.

Try to sleep in a position which helps you maintain the curve in your back. Sleeping on a soft bed or couch can strain neck and back muscles since the three curves of the spine are not adequately supported. Also, avoid sleeping on your stomach as it can cause additional strain on the neck and back. Select a firm mattress that does not sag and keeps the spine aligned. If necessary, place a board under your mattress or place the mattress on the floor. The best sleeping positions are on your back or side. A pillow can be placed under the knees when lying on your back to take pressure off of the lower back.
