After the mattress inflated naturally I put on my bed box spring I laid on it. It hugged my curbed in the side of my body. Different than other mattress’s I’ve used in the past. No squeaky sound. No to poke through springs. It’s safe and soft mattress. I can move around without waking up my partner which I couldn’t do with my old mattress. This is much improvement compared the the last one we tried. I think we will stick to this mattress. We definitely recommend this mattress.
