too soft and narrow

This mattress is extremely soft, much softer than other medium support mattress. It is also very narrow too. I bought a queen size, however it only has the size of full mattress. Don't waste your money on it. The material feels cheap as well, you can feel all the springs.

Very comfortable

[This review was collected as part of a promotion.] I slept very well. I was able to sleep comfortable and straight hours without waking up like I usually due to body ache. It really has helped me sleep through the night since I started sleeping in it. Not to mentioned that everyone in the family has enjoyed how comfortable is it. Also, to add that it comes in a box! I definitely recommend.

Very comfortable bed

[This review was collected as part of a promotion.] The Sealy Essentials 12" Hybrid mattress is very comfortable to sleep on. The mattress came in a box and unpacking took less than 5 minutes. The mattress seemed to expand within minutes but we waited several hours as directed. There was not a strong odor as you sometimes find. This mattress is a little more on the plush side and the foam layer contours to your body but you don't get a sinking feeling which is exactly what I was looking for. Overall I would recommend this mattress.

Wonderful nights sleep!

[This review was collected as part of a promotion.] This mattress is so comfortable, it really has transformed how I feel getting up. It has a nice bounce to it from the springs which I didn't realize it had being a foam mattress as well. It's well made and from a great brand as well. I definitely recommend giving it a try!

Comfort With Convenience

[This review was collected as part of a promotion.] Getting a queen size mattress in a relatively small box seemed strange, but I'm truly impressed. The mattress is heavier than our previous traditional mattress, but since it came so compact my husband was able to carry it upstairs by himself. The unwrapping process was pretty cool, with my husband asking if it was going to be like those refrigerated biscuits in a tube, if there would be a loud "pop" at some moment. There was no "pop" but the mattress reached it's full size in a matter of minutes, we read that it could take up to 48 hours, but this one was practically instant. I also read that there could be an odor due to the natural latex, but we didn't experience any. I really love the level of firmness in the mattress, I'd say it's medium, but with the added top layer of extra cushion. I generally sleep hot and couldn't deal with the last mattress that I had with a foam top, so I was leery about this one, however this mattress has not had me waking up sweating. The drawback to this otherwise very nice mattress is that there isn't much support at the sides, which is probably not something that can be addressed in a "mattress-in-a-box", if you roll near the edge you can feel like you're about to fall off and as someone who always sits on the side of the bed to put his socks on, my husband also doesn't appreciate the lack of a more defined edge. Overall though, I'm pleased with quality of this mattress.

Soooo comfortable

[This review was collected as part of a promotion.] I've been desperate need of a new mattress but didn't want to spend over $1000 for one. These mattress in a box are sooooo good. I've purchased one also for my parents and it's the most comfortable mattress ever.

Feels like a cloud

[This review was collected as part of a promotion.] Great mattress without a hefty price tag. The hybrid model is the best of both world. The foam top feels like sleeping on a cloud. It conforms well to the body so it's extremely comfortable. Easy delivery and unpacking as well!

Superior Comfort!

[This review was collected as part of a promotion.] I have just slept my 7th night on this Sealy Essentials 12" Hybrid Matress-in-a-box and it has been a week of pure bliss! I could not wrap my mind around the idea of a mattress coming in a box. When it first arrived to my door, I thought "how could there possibly be a queen size mattress in there?!" But let me tell ya, there was! It was simply amazing how this Sealy mattress would fold out and pop up! It was a fun pleasantly surprising watching the process! Within minutes, this mattress-in-a-box went from a thin strip to a full and plump mattress! I found it is best to open the box in the place your mattress will go. We carried the box upstairs first and then opened it. The box is certainly heavy, but it's compact enough that it's easy to maneuver using two people. It's a beautiful color. I love the pattern on the top. I laid across the bed for the first time and instantly felt the comfort I have been looking for! In fact, I was so comfortable I laid there long enough and literally dozed off! I have had the best sleep this week! It is far better then the one I was sleeping on. This mattress is quiet. It doesn't make noises when I roll over like the other one did. I can get in and out of bed without even disturbing my husband because the memory foam basically "holds" us in our own space without any disturbances. It's just so soft! I love the durability around the edge of the mattress that allows me to get out of bed easier. I feel a coolness in the mattress when sleeping. This is important to me because I don't like sleeping in too warm of a temperature. I also love how the pain I would get from laying in one spot on my other mattress has completely left! I find myself excited for bedtime, just so I can go lay on it! I give this a top rating and would recommend to all my family and friends. I love it so much, and find the benefits it offers so great that I plan to buy another for our guest room! Phenomenal product, Sealy!
