love the mattress but 4 stars because the cover is so slick we actually removed it to get the sheets to stay on. sams find a less slippery cover! i would buy again knowing i would be replacing the cover instead of trying to make it work as is. still very affordable.

DREAMY! We purchased two more expensive mattress only to return for these. We are not fans of memory foam and this is a true hybrid. We choose a king split - (2) twin XL, one plush and one medium. Heavenly! The plush is very soft and the medium is on the softer side as well. Personally, I do not feel the “cooling” aspect, but they are not hot like most memory foam. Fluffed up in a couple hours and slept on them same day. Hopefully they will hold up overtime, but you cant beat the price! Highly recommend!

Purchased the "firm" version of this mattress a couple of weeks ago. Slept on it for 5 days now. Very comfortable, and the cooling top is great! "Firm" = support and a little give. Definitely not a hard mattress. No harsh smells were noticeable when the mattress was unwrapped. The box was a little beat up but the mattress was not affected. I would purchase again. Melissa H.

Like other people reviewed, this mattress arrived with a defects. On one side it was 4 inches short, on the other side it was 2 inches short. The foam was also misaligned to the base so the coils stuck out 2 inches on one end and the foam stuck out 2 inches on the other end. The cover also fits loose and theres no foam protecting the bottom coils so they pushed through my bed slats. Sam's Club was great about taking care of the problem. They offered a return or replacement. I opted for a return and purchased another mattress. Sam's Club sent out somebody to pick it up for disposal. Some people had good experiences but I'd recommend going with something else.

Not a good mattress felt great for about a month. I should've had red flags when the mattress arrived too short from my other twin xl and more narrow. Seems like this one was definitely defective maybe? Not wanting to keep it either because my deep sheets don't work on it as well!

Bought roughly 6 months ago, full FIRM mattress. Allowed this to "inflate" for 72 hours before sleeping on it. I am 5'6" roughly 200 lbs and tend to sleep on my stomach and back. I rotate the mattress every 4-6 weeks. Measures at roughly 13-13.5 inches after the 72 hr period which I consider close enough to the description. Initially felt it was too soft for me, however I think it matches the "firm" description when compared to other hybrid/memory foam mattresses. So far I don't have an indention where I sleep, but I do think the regular rotation is making a difference there. I would certainly buy this again; I have recommended it to my friends since buying. Only gave 4 stars because it does get a bit warm as the night goes on which again may be par for the course when it comes to memory foam mattresses.

We bought two MM 14” medium-feel hybrid mattresses, and we could not be happier with our purchase. We sleep supported—without sinking in—and cool. And we rest for a minimum of 5-6 hours before awakening. Then it's back to sleep. These are the best mattresses we have ever owned, and they are competing against high-end, ripoff-priced mattresses that we owned previously and that cost $6,000 and $7,500 (specialty brands from San Francisco). If you need a mattress, don't delay. Members Mark will save the day.

Ordered King Medium. This was my first hybrid bed in a box. I have had the mattress for 6ish months... i am a side sleeper. Female, 53, 165 pounds and 5'4. At first it was good...but now my hips and lower back are hurting me. BTW I take Aleve at night too. The mattress has nothing wrong with it...no sag or indent. Just not working for side sleeping.

Big man needs support and coolness. I got both. Great purchase for me.

Very comfortable mattress. I will be buying more of these soon!
