My husband and I have been waking up with lower back pain for quite some time on our "NEW" mattress! We spent quite a bit and were so upset that it was way too hard! I ordered this memory foam topper and just love it. Had to let it lay out for 5 days and nights to really air out. The night we got it on the bed we slept all night long! Just love it! So comfortable, very soft!! If you don't like a really soft bed, don't by this one. But we love it!!! So soft and comfortable!
