With mostly good reviews, my husband and I thought we would save some money and get a decent mattress from Sam's vs overpriced ones elsewhere. Man, were we wrong! When we first tried it out we thought "this is nice". It was softer than the medium-firm description. But the more you lay there, the deeper you sink. You get sweaty it's so hot. And uncomfortable. We had a crick in our neck the first few nights we slept in it (notice "in" it, not on it, because you are in this thing!"). You sink so low as your head stays on your pillow that your neck is in a very awkward position. We added a topper that helped some, but the mattress still sinks and sucks out topper in with it. It stinks right in the middle. We both wind up in the middle in this hole every morning. It's like a nest. A nest made by some gigantic bird that thinks we are its babies. If you like to sit up on your bed to watch TV or read, you can forget it with this one. Your bottom sinks in as you sit there and your little legs hang on to the top to keep you from getting completely devoured by the mattress. Reminds me of an old episode of "The Twilight Zone" or "Tales From the Crypt", I can't remember which one, but the bed was eating people. I really do not want to go through the hassle of trying to return this bed, especially because there is no way to get it back in the box. I don't live near by my Sam's Club either. On top of this mattress ordeal, they charged me twice for another item and can't take care of giving me a simple refund over the phone. They want me to drive sixty-six miles round trip to do that. I am very disappointed in customer service right now.

I know this mattress is an inexpensive mattress, but I believe the top layer of the mattress should not have stretched/separated to the point that it causes pain. I am older and have no way of returning it fully expanded. Note: The bed was a dream the first week and I slept better than I had in a very long time. I was absolutely delighted, but my euphoria is rested and low pain was short lived. This mattress should not be advertised as being compatible with the adjustable base. The base was purchased from Sam's Club as well.

I have had this mattress for a month and so far I really like it. It had a slight odor upon opening but I left the fan on as it fluffed up and the smell went away fairly quickly. It was not bothersome at all. I was used to a very firm mattress so this one was an adjustment but I actually like this one much better than any others I have tried. It is soft enough on top and firm enough underneath for good support. I have been sleeping better on this mattress than others I have tried or bought in the past. It is very reasonably priced and I am very happy with it. I highly recommend.

**** Full size, Firm **** If you’re looking for a firm mattress, this is not the one to buy. The mattress I received could be considered "medium" at best, which was a major disappointment. Unfortunately, my frustration didn’t end there—it only increased when I tried to return the item. I contacted Sam’s Club to request a return. Given the mattress’s size and that it had expanded after unboxing, I asked them to arrange a pickup. They agreed and scheduled one with AIT delivery service. But after more than three weeks, I’m still waiting for them to confirm a pickup time. During this period, I’ve reached out to Sam’s Club four additional times. Each time, they claimed that AIT had tried to call me, but I hadn’t answered—which isn’t accurate. I made sure to answer every call, and there were no voicemails left, which would have been expected if I missed a call. Sam’s Club also assured me that AIT would contact me by both phone and email, but I haven’t received any emails (I checked my spam folder too). It feels like there is a complete lack of coordination between Sam’s Club and AIT. In my latest conversation with Sam’s Club, they promised AIT would contact me within seven days, but at this point, I don’t have much faith in their word. My takeaway from this experience: Avoid buying any freight item from Sam’s Club. I had a similar issue with a previous Sam’s Club delivery, where a “white glove” item was simply left at my front door. Although they gave me a 10% refund for the inconvenience, I ended up spending more just to bring it inside and set it up.

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.

Supposed to be medium firm, but there is NOTHING firm about it! Sit on side and sink all the way down. At least 2 inches wider than normal king. Yes, we let it setup before use, but it only rose to 10 inches. Box said 12! Should be labeled extra squishy! I want my old mattress back! Totally disappointed with this purchase! Btw won't allow me to give zero stars!

astronomical mattresses. Definitely choose this one over the new hybrid one. My entire household has these in all sizes. I bought my first one about 5 years ago and it hasn't had any impressions or imperfections. highly recommended. It has significantly reduced my lower back and hip pains. even the dogs love it

I purchased 2 Twin XL 12" medium mattresses to use with a King platform bed. While the mattresses expanded quickly, had no smell, and a perfect medium feel (not too soft/not too firm), they are not anywhere close to a Twin XL dimensions (38" x 80"). Within 15 minutes of unboxing, they each expanded to nearly 42" wide. Height only got to about 11" as well. 84" wide will not work on a 76 1/2" wide bed. I ordered online so they will be picked up, but it was a complete pain to have to plastic them up again for pick up.

First it did not raise to 12" . Almost 11". The mattress is super soft and it sucks you into it. When you try to get out it bottoms out to the frame. It's the most uncomfortable mattress to sleep on. Sam's should be ashamed to produce this type of product. It's true, you get what you pay for as we thought we would try it out as we bought another brand similar to this and it lasted about 6 years and was very comfortable but that was not the case with this one. Don't waste your time taking this one home because you will be returning it. I hope they let us return it!

I took a chance by reading all the great reviews. Well that chance was a gamble I lost. Where do I start. First I let it air out for 72 hrs 24 more hrs than recommended and it still never fully inflated. Second this mattress is totally uncomfortable. I’ve slept on cots while deployed that was more comfortable. This was $400 plus bucks down the drain that I couldn’t afford. You live and you learn.
