The mattress is comfortable but sleeps hot. The mattress height has yet to decompress to the full 12" height in the advertised description. The width of the mattress budges obviously by 2"-3" overall. I will be returning this mattress as soon as I am refunded for the mattress I purchased online through Sam's Club. Today is the 9th business day since my online return was picked up. The online return pickup process was a pain staking 45 days. Sam's Club Members beware!

This mattress was labeled "Medium- Firm", which is the firmness I was looking for. Not only is it not firm at all, it feels like a soft mattress!! It's as though it got mixed up and thrown in the wrong box... terrible. I'm trying to make it work because I got rid of the packaging and can't take it back, but it's awful to not get a good night's sleep. I gave it one star instead of zero because I appreciated the convenience of being able to transport it without a truck. But I've regretted this purchase every night and morning. Buyer beware!

This is not really a firm mattress. Some areas of the mattress are softer than others. Our backs have hurt every morning since the purchase of this mattress. I would love to return it but there is no way for me to transport a king mattress back to Sam's Club. It was delivered vacuum sealed in small box and then expands to full size.

Mattress did have a chemical smell for a few days. It does sink at the edges when you get on and off the bed. It did take half-a-day to firm up. AND this mattress is the perfect balance of sinking into the mattress but not sinking too far. It's one of those mattresses that will not hurt your hip or shoulder if you stay in one position for hours. But you do not feel like you are on a hammock:) You feel like you are on a well made, expensive mattress that was a bargain!

Mattress is made from cheap foam. Definitely not high density foam. Mattress sinks when laying on it and is not medium firm support- more like soft plush. Spend more money for a better quality mattress. Took this mattress back within 1 week of buying.

Two nights used and it created a wrinkle in centre.

Felt more like soft rather than medium firmness. Way too squishy for my liking.

Pros: very cooling, very comfortable. a medium feels more like a plush so that was a nice surprise. good proce point. Cons: only lasts about 1.5 years before body impressions are so deep it kills your back. and this eas rotating the mattress religiously every other month. but for 499 it was worth trying to see how it worked. would probably be auited best for a guest room where it wouldnt get everyday use.

We are 80 and we had a tempur-pedic. We really love this mattress,, But,,we put it on our base that goes up and down, which it says you can and the mattress has developed a big lump half way down, from putting it up. We have only had it a month and we may have to take it back, because the bulge won’t smooth out. I will take a picture and submit again

I purchased two Queen Medium mattresses and one King Firm for my Airbnb properties. After a year of hosting as a Superhost with Guest Favorite status and maintaining all 5-star reviews, I've found that about 85% of my guest reviews specifically mention how comfortable the beds are. Because of the overwhelmingly positive feedback, I decided to purchase the King Firm mattress for my own home. It has exceeded my expectations—it's incredibly comfortable, supportive, and cozy. It truly feels like sleeping on a cloud. I couldn't be happier with my purchase!
