This is a great mattress. It is so versatile and so soft. At the moment we are using it as a pad for the floor to play with my baby grandson. It’s perfect as he is learning to sit unassisted and crawl. I got the 4” version for actual sleeping and I do wish I had gotten a thicker one, but I am still extremely satisfied.  It comes in a box so allow time for it to expand. Awesome product Wayfair!!
