For many years, at least since 1995, I have had lower back pain upon waking in the
morning--my back
pain is only due to laying in a horizontal position. At one time, I tried the Select Comfort bed, but that did not help. Once I stand, the pain goes away or mostly ceases. From x-rays, the very lowest disc is mostly flattened, and there is some arthritic growth present at the lower spine. I have been able to get by because, as mentioned, once I got up, the pain diminished.
