I read reviews for this before i purchased it, and was a little skeptical about purchasing it. Received my order on the date of expected delivery. After I rolled it out, it pretty much inflated to the right size right away. Didn't experience the odor other people had mentioned from this product. Let it set all day and that night put the mattress cover on it and slept on it. I absolutely love my new mattress topper. Exactly what I have been wanting and what I expected to receive and more. I would recommend this to anyone.
