Edit to update: I love this mattress and am updating my review from 4 to 5 stars. It is so comfortable. I'm not waking up to reposition in the night. No hip pain. I'm not having issues with being too hot or cold. I'm very happy with this mattress.

This mattress came rolled up in a box. Unrolling it was easy. As soon as air got into the plastic, it started filling up and was full-size within a few minutes. It comes with a cover with a zipper, which is nice. I would say it's medium-soft. I was interested in this mattress to try and alleviate pressure points. My husband is worried it may be too soft, but that's not the mattress's fault.
