My hubby and I both have bad backs. We tried 2 different bed models from a different manufacture and for us, they were so uncomfortable from the first night, and only got worse each night. There was no way we could keep either of these beds and returned them. We decided to move to different bed maker. After reading the reviews for S& F, it sounded too good to be true. We went ahead and ordered Sterns and foster, Lux estate soft pillow top, and we have had unbelievable sleep, since the first night. No "breaking in required." Ordered directly from Stearns and foster online. No hassle, delivery, and received it in less than 2.5 weeks. Great quality and even signed by bed maker. To me, that shows they really care. The only problem now is that it is so comfortable, we don't want to get up. Good problem to have!! We are so happy.
