[This review was collected as part of a promotion.] I'm amazed by the combination of quality, comfort, and convenience of this Sealy Essentials 12" memory foam mattress-in-a-box! The mattress came vacuum sealed and rolled up, and was easy to carry into the house and upstairs to my bedroom. It was almost fully inflated within a few hours. The mattress is incredibly comfortable and soft, but firm and very supportive as well. I sleep great on it. It doesn't sleep hot in my opinion. I definitely like it better than a traditional pillowtop spring mattress.

[This review was collected as part of a promotion.] I have had this mattress for a good while now for me to personally know how it is. I absolutely love it!! It's firm but also has a somewhat soft firmness to it as well, the 1st night my husband was just like "I don't like, my back hurt" but by the 4th day he's had no back problems and he's a side sleeper. I'm a back sleeper and I used to wake up every morning and have to pop my back because of how bad our bed was. We even had a purple mattress and sent back within 3 months because we could tell by a couple days that it was pure garbage. I love how it goes back to original shape after sleeping all night. I'm not sweating anymore from how our old mattress retained heat so bad. This by far is the best mattress we have had in the past 10 years, we went through 3 and that's alot. I'm hoping this one last us a long time because I love waking up everyday with NO back pain!! It has been a God send on every day life. A great mattress will change your daily life and I highly recommend this one! The photo is before I put it on the bed right after unboxing because we had to get rid of old mattress first.

[This review was collected as part of a promotion.] Everyone always told me you need a hard bed for your back, but I sleep on my side and I would wake up with hip and shoulder issues. I tried getting a memory foam topper, but it was too soft. This bed is PERFECT. Not too hard, not too soft. I highly recommend if you're a side sleeper and you're having trouble finding the Goldilocks zone with mattresses.

[This review was collected as part of a promotion.] This is a great option for anyone waking up with a sore back. It really help you sleep more level and less morning aches. I would recommend to try. It came is a large heavy box, so make sure you have someone around that can you bring it inside

[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!

[This review was collected as part of a promotion.] These new mattresses are so convenient. They arrive in a box that can fit in most large sedans or small SUVs. They are easy to carry up stairs if you have two people. The mattresses are tightly air packed and very dense, so the box is heavy. Once you get it opened and unsealed, you let it expand to it's maximum size and you're good to go! I think 12 inches is the perfect size for a memory foam mattress. I have a 14 inch in my other bedroom and it's just way too high up and I have trouble getting fitted sheets to stay on. This is the perfect blend between comfort and height and support. My back usually has trouble adjusting to a new mattress, but I didn't have any pain switching to this one as my main mattress. Overall, this is a winner. Easily 5 out of 5 stars.
