[This review was collected as part of a promotion.] I am so very happy with my new Sealy Essentials 12" Memory Foam Mattress-in-a-box! Getting a mattress in the mail seems impossible until it actually happens! The box arrived and seemed like a joke because it was so small. It was extremely heavy, however, and I felt terrible for the delivery dude that literally had to drag it up to my door. We opened the box to this super-tightly rolled mattress that was in the shape of a giant sausage link. The mattress was completely compressed in a vacuum-sealed plastic bag with yet another plastic bag surrounding that one. Once we released the mattress, which was as easy as cutting open a bag of chips, it began decompressing immediately. It was completely decompressed after less than two hours. This mattress went from a tight, sausage-shaped plastic roll to a huge, queen-size mattress so quickly! The memory foam it is made with is utter comfort to the max. The item comes with a limited 10-year warranty that covers any permanent human sunken marcations that may form over time, which I imagine will not happen or else there would be no such warranty! Lying on this beautiful mattress is like a dream! Memory foam sometimes takes a few weeks to fully accommodate its user, so I know that this will just keep getting better over the next month! As if it could!! We love it already after just a week! Everyone has heard of the brand Sealy, and I read that it's been around since 1881. That says a lot about the quality of their products, and this is indeed a great introduction to quite possibly my new favorite sleeping brand in the world! I took one star off this otherwise awesome mattress due to the fact that only the box it came in is actually recyclable. The two other giant plastic bags in which the mattress was held are not recyclable. The waste is way too much for the simple convenience of having a mattress delivered like a sausage to your house, especially considering the backache it gave my delivery guy!
