Product arrived super fast. Followed directions and allowed the mattress to fluff for 48 hours. Out of the box, its rolled up and very flat, so that step is essential to follow. It had a slight chemical smell but that went away quickly and didnt overwhelm the room. After the fluffing time was up, I decided to try it out and was admittedly a little disappointed because of how firm it is. Hopefully with some usage itll soften up.
