We bought the mattress only, as ours was a good few years old. The old mattress was not helping my back, I had difficulty turning over, and had many disturbed nights. The new mattress took a few nights to get used to, simply because it was so different to our old one. I find that it's warm, soft, and the mattress seems to mold around my body, supporting my back. I am amazed at how this mattress, has made a huge difference, to the quality of my sleep, and for its comfort. It's the best purchase we have made in a long time.
