I couldn't decide whether to buy this product or not. I read all the reviews and then went back to the site a few days later and read them again. I have a 10 yr old mattress that I was thinking of replacing but couldn't afford the one I wanted without charging it and I didn't want to do that. I am so glad I bought the Rejuvenator! My mattress really does feel brand new. Now, the best time of the day is when I go to bed @ night and the worst time is when I have to leave it in the morning. The Rejuvinator is a great value, even better than I hoped it would be.
