I use to think I didn't like this type of mattress until my friend couldn't say enough about how much they liked theirs. So I decided to give it a try. I love that it shows up easily at my front door and easy to roll out. It took me a couple of weeks for me to adjust to the heat that came from the the mattress for me. Other people have written about this as well. Customer service was helpful, suggesting to try without mattress bad or that I can return if still not happy. I went back to using the mattresss bad, lightened my top covers and my body seemed to adjust. It was worth the wait because it was and is super comofortable. The warranty is awesome, too. I kept my box spring under it. I was getting a back ache from my old mattress. That went away the first night. Seriously. I would recommend and buy again.
