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.

So I’ve only ever owned cheap spring mattresses they were way too firm and I’ve had back problems for as long as I can remember and I’m only 27. We got this mattress and I woke up so refreshed feeling. I need something that helps my pressure points and this did it! It does not sink me in but it curves to my body very lightly. I’m a side sleeper so this helped so much. I normally wake up with side pain and not anymore. Never woke in the middle of the night like I normally do. Both my kids have memory foam already but they’re twin mattresses so when we are ready to upgrade them I’d love to buy them the Members Mark one!! I never had any issues with a smell like the other reviewer and I only waited 24 hours it got up to 12 inches immediately but I still waited a day. Thank you Sam’s for selling an affordable comfortable mattress!

Do not buy if you have any form of back issues. I let fully expand before sleeping on it, I would wake through the night with lower back pain which isnt uncommon and reason why i bought bew mattress so i didnt think anything of it. By morning the pain is completely unbareable ive never experienced pain this bad. There is zero support with this mattress and is on the plush side nothing medium about it.

We purchased a full-size, firm mattress for our spare room in February. It's now June. I waited to leave a review, so I had plenty of time to try it out. It is definitely not firm. I sleep on it 5 nights a week. It's soft, and your body sinks. It might be firm for a child, but anyone over 100 pounds would not say it's firm. Would not recommend or buy again. .

Bought a cal king a year ago and am extremely happy with this mattress. I'm a side sleeper and found it a bit firm, even in ultra plush, but I bought a Serta memory foam-and-"fluff" mattress pad, which made it exquisitely comfortable. Now the mattress and sleeping is perfect and absolutely delightful for me. I love getting in the bed, so look forward to those few minutes of enjoying the mattress cushy comfort before drifting off to sleep. My 75 pound dog jumps up in the night and I don't feel it at all. I only know she did it because she is still there in the morning. LOL Will buy another, smaller, when I relocate in a couple months. You can not beat this for the price. I couldn't be any happier with it. Seriously

We bought a new mattress for our new camper. Slept like a baby the first night, and I never sleep good the first night out. We were amazed. So when we got back home, we ordered another mattress for our bed. Coming in a few days and I cant wait! This is a happy camper!

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.

First we purchased one for our toddler’s big boy bed. After trying it out for a month we ended up buying another for our own bed. For a foam bed, it’s pretty great. I’d like to see the edges more firm but that seems to be a problem with foam beds in general.

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.

Love the bed I own 2 a full and a queen the queen I had to get a replacement shortly after purchasing the zipper on the bottom of the cover did not zip came like that flipped over to try and zip but won’t work they replaced no questioned asked I’m really happy. They are not firm they say firm but they are quite soft you sink in them, i sleep every night in this bed I have no aches and pains it helps a lot.
