This mattress arrived quickly and conveniently wrapped and sealed for immediate out of the box use. Once I opened the box, it was easy to pull the mattress out by the extra plastic on the top, I placed it right on the bed and cut the plastic. There was no scent or any type of smell, it inflated fully within minutes and was ready to use the same day. The memory foam was very comfortable. Laying on it feels firm and soft all at once. Having slept on it for a few weeks, I no longer feel the shoulder pain or the sciatica discomfort in the morning.. Valentina. Collegeville, PA. Tue Nov 23 2021

We got this for a Murphy bed (also purchased on Wayfair) so we could easily store it when the Murphy bed was not in use. We are VERY happy with this mattress! It has a thick, Jersey fabric covering it which makes it so soft. The mattress itself is very comfortable and not at all like a stiff, hard foam. You can feel that its memory foam and our guest love it. It’s easy to fold up and move thanks to the attached handles. One person job. We definitely recommend this mattress!. Jb. Illinois.
