The media could not be loaded. Originally I got this mattress as a cheap alternative to tie me over until I could make a decision on buying a new mattress. The prices of mattresses these days are so overwhelming. I read all the reviews and I compared the structure to expensive name brands. I have never made a better purchase! The quality for the price is unbeatable. I was surprised at how firm it is as I expected it to be flimsy. Not at all! It’s firm but has a very nice soft top. Everything about it is exactly like the description. The set up was easy and fascinating. As hard as it was I did let it sit in my living room for 3 days before putting it in my bedroom. My sleep has improved and I move a lot less during the night. My back pain has also improved.

An absolutely easy bed to put together and the durability is amazing with a firmness isn’t there if you’re looking for something soft & my children love their mattresses. It’s not meant for someone with back problems but the sleep quality is amazing It certainly supports the body as you sleep or just lay in bed. The functionality is lovely as well.

I've been needing a new mattress for a LONG time but shopping around is such a hassle & they're so expensive. I have been looking into these gel hybrids & reading all the reviews I could and when I finally decided to take the plunge, this one just happened to be a lightning deal for 40% off and had some of the best reviews I've seen. I was really hoping shopping online without trying it out wouldn't be a mistake but so far, I think I made a great choice! I purchased the 12" Queen sized. *Please be prepared when you open this mattress, it will unfurl and unroll itself QUICKLY & it can knock you over! I read that in a review somewhere so I planned ahead 😂 I put it on the box spring before taking it out of the plastic while it was still rolled up & aimed it so it would unroll towards the foot of the bed. *It only took mine a couple hours to fluff up, everything says 24-72 hours but that's probably for the mattresses that aren't taken out of the plastic & laid flat immediately after delivery. *There was a very slight smell when I first unpackaged it from the plastic but it wasn't an unpleasant smell at all, it wasn't overwhelming and it went away completely within the couple of hours it took to fluff itself up. This will be my first night sleeping on it and I'm so excited for a good night's sleep on a good mattress 😭😂 just from sitting/laying on it for the last hour or so, it already feels amazing & high quality, especially after attempting to sleep through the night for the last year on my previous mattress. I will definitely come back and update in a couple weeks or a month!

This bed is comfy and great for the price. No bad smell either. I gave it 4 stars because it says medium firm but it is not. This bed can easily be named medium soft, if not just soft.

I have had this for over a year now and I can say that it is a very good mattress. It has held up very well and I spend most of my time in bed as I am basically bedridden because of a back injury, so it's had quite the workout. Just remember to turn your mattress every 6 months or so, so that you don't get the "pockets" from your butt sitting in one place, lol. The memory foam and the padded bumps on top still feel like brand new. Very comfy and a great price.

I was scared to purchase my first mattress, especially on Amazon. The comfortability of this mattress has blown our minds. Will order another one when the time is right. Seems like it will last forever.

This is one of my first reviews- if you are considering this mattress BUY IT. I didn't spend a lot of time searching, I actually dreaded this process of finding a mattress online after a few bad ones but chose to go this route again for a queen size mattress for my parents RV that we would only sleep on a few times a year. I read the basic review summary and went with it(a first for me, I usually scan reviews)! I am SO SO happy with this purchase. First, its comfort level is right on. Medium Firm, it didnt even need memory foam. Both my husband and I are 5'9 and I weigh 150, he weighs 185, we also shared the bed with my 2 year old.. I didnt even feel my husband move from the bed both nights(im a super light sleeper). Length was great. I am so pleased with this mattress I will absolutely buy another one for our guest bedroom. I hope this review will help someone else searching for the right mattress. I will say, we should have let it air out from the bag when we received it, but my dad opened it and we did not have time to do that before sleeping on it. But, I didnt notice a smell I dont think, just wish I would have been able to let it air from the plastic.
