After much research we chose this firm, king size mattress. After originally leaning towards a hybrid mattress with springs and foam, we are extremely pleased with our all foam mattress. IMO, the addition of springs just adds an unnecessary quality risk with the way these "bed in a box" mattresses are packed. We had concerns about returnability and felt that a Sam's Club product (Members Mark) would be more highly supported in case there were issues. This mattress gives firm support, yet is comfortable whether a side sleeper or back/stomach sleeper. Without a legitimate firm mattress we are subject to back discomfort. After 7 nights of use we are happy to say that we are extremely pleased with our choice.

We had this mattress less than 2 months and the foam warped and bulged and is sticking up inside the mattress. We are disappointed not only because we spent over $400 and the mattress lasted less than 2 months, but it would be entirely too difficult to return as it comes vacuum-packed in a bag/box and is quite heavy. Attaching pictures, although I'm not sure if you'll be able to see the warping. Buyer beware--this is a cheap item.

I read other reviews and thought I could get away with some of the issues noted about this mattress but no. This is error purchase for me. The mattress is softer than the mattress I'm trying to haul. I literally sink into this mattress. I was expecting medium firm but it's not near it. Planning on returning it. My old mattress lasted over 10 years, not sure this new mattress would make half of that. I brought on sale so i'd say penny wise, pound foolish. Cheap is expensive! Also gives me heat not cooling at all, makes me uncomfortable overnight.

We're at day three on our Members Mark mattress, after returning a Casper mattress that we purchased. We found that the Casper was very stiff, and didn't breathe. On the flip side, this new mattress is super comfortable, and breathes well. It says cooling gel, but I haven't really felt cooling (It just has better airflow). For the price, I would recommend this to anyone.

We bought this for our oldest child a few years ago and it hasn’t been destroyed/ sagged and now this one for our youngest. So comfortable I’m thinking of trading our bed for this too. I have no back pain when I sleep on one of their beds. Only downside is if you like to sit on the edge of the bed, you will sink.

We bought two of the XL Twin Firm mattresses. Before this purchase we had a sleep number bed. After20 years I still tossed and turned all night. With these new mattresses I placed a 1inch memory foam topper on them. I no longer toss and turn at night. So very comfortable on these mattresses. They came rolled and vacuum sealed in individual boxes. Never would have thought they would be this amazing. So glad we got them. Don't miss the sleep number at at.

Couldn't have been better. Mattress arrived 7 days prior to expected delivery, and though the box was heavy, maneuvered it into bedroom, slid mattress out of box, lifted it on platform, and off it went, rapidly filling. Rapidly. Medium firm and looks good. Perfect for overnight guests and children

I have on one of these Eight months now .. Always had the 3000.00 Temprapeutic Mattress.. My temprapeutics usually lasts About four years, i'm a big guy I've owned 2. I have enjoyed this sams version as much as the expensive version.. I've seen people complain about the Smell , That's something you have to get use to with any memory foam mattress.. My only dislike, It has about a half inch topper that wrinkles up and there's nothing you can do about it . (temprapeutics have zippers) This is reason it's not getting the full five ... price value ,five stars.. Comfort level ,five stars..

I have purchased the Serta mattress at sams and the quality is way different. This mattress is very weak around the edges and the corners are worse. If you are using a platform bed that is slatted the mattress will push right through so you will need some kind of support between your mattress and the slots. I would recommend the serta bed in a box over this one for sure.

If you’re looking for quality sleep don’t hesitate to order this mattress. This review might be a bit premature as I’ve had the mattress less than a week, but I am impressed!! I will update my review if warranted but for now this mattress is 4 layers of pure heaven! Cool to the touch, very comfortable and fit on my existing box spring.
