This item came vacuum packed so we had to let it sit for a while for it to take its form. It is pretty heavy and feels good to the back. Not too soft not too firm. It is made of decent material. So far we don’t see any issues with it. This mattress is a full size and 12 inches thick.
**Update on initial review
Brought the rating down from 4 to 3 as the mattress cover was too loose and moves around. Can’t get a good grip of the mattress to put it in it’s proper place because of the cover. Still ok to use once it’s in place.
