SealyFoam Bed in a Box – 8 Inch, Firm Feel, Twin XL Size, CertiPur-US Certified White

I researched, and tested in person, a bunch of different mattresses. I found this one on a whim when I searched online, I was skeptical buying online without being able to test it, but I trusted the reviews. I’m glad I did.PACKAGING: The package is pretty heavy, I’m a strong, young guy and it wasn’t a back breaker but I could see some people struggle with it. After unwrapping it, it puffed up to full size within the first half hour, I guess I’m one of the lucky ones. I’ve seen it take a few hours in some reviews.FIRMNESS: I laid on about 10 different memory foam mattresses during my search, this is definitely on the softer side. Everyone has different interpretations of “plush” or “firm”, but this one is definitely a little on the softer side. You’ll feel yourself sinking into the foam, so if you like firmer mattresses, this one probably isn’t for you.HEAT: I never knew heat was a thing with memory foam mattresses until I read reviews, but I kind of got the hint when I noticed “cool” being in a lot of the advertising. Well it’s a real thing. I definitely felt the heat, I like being warm, so it didn’t bother me personally, although I did have to take my comforter off at one point because I was sweating. I could definitely see it bothering some people.PRICE: I thought it was a great deal. Bob’s Discount Furniture wanted $200 more for a generic, no name brand, version of the same thing. Sealy is a great brand, and the price is very reasonable based off of the quality and the brand.SMELL: I’ve seen some reviews really complaining about smell on other mattresses. It has a slight “new plastic” smell, but it’s definitely not overwhelming or unbearable. I stopped noticing it after the first few minutes.OVERALL: I can deal with the minor issues like the heat. As soon as I laid on this mattress I could feel my back and shoulders loosening up. I can sleep on my stomach now, pain free, but can’t do that on most other mattressses. It’s a great buy, and it really helped with my pain/discomfort! Just be aware of the heat and firmness, I’m a very easy going person, not picky, I could see those being issues for some people!

Very happy with the purchase

Not a 12 inch mattress ( it's 10 1/2 inches).Very soft. You have to lift yourself out to turn on your side and I weight 130 pounds. Sides are not firm and have a lot of give. Could be nice for young children. I would be hesitant to put in a guest room. Sealy Conform Essential is a much better choice.

Sealy should warn you about how hot this bed is, you feel suffocating. Besides, it never fully expanded on one side.I have purchased already 3 cooling pads with no success. The mattress does not breathe and you feel like trapped in an oven. Really a bad experience!

Expected more support. More on soft side than firm. Slept extremely hot and sunk in making movement difficult. I’m 5 ft and 145, I have injuries (Repetative Stress on wrists and elbows) that were pronounced attempting to sleep on this mattress. In the return process which is turning out to be quite a hassle. Don’t order unless you’re 100%sure this is the right mattress for you. I’m learning the hard way.
