Husband and I love this mattress. Let it completely fill before judging. It is a plush feel on top with a medium firm feel lower layer. No sinking in. We are both hard to please with mattresses and love this one. I am a side sleeper and hubby is a combo sleeper. Just works in all positions. Very comfortable! Way to go Sam's!

This mattress claims to be medium/firm. 100% not the case. I should have read the reviews because it is way too soft. To make a long story short, this is the worst mattress I have ever bought. Please don’t make the same mistake I did and purchase this bag of feathers.

**** 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.

After getting an adjustable frame decided time to change mattress. Biggest problem was getting the old one off and ready for disposal and getting the plastic off the mattress was bit of challenge being careful not to cut the mattress. Once in place it began to hiss and start to expand quickly. Was surprised it only took a few hours to expand to 11 of its 12 inches! Very comfortable. Have seen reviews saying too soft but they must like sleeping on a rock as this is advertised as medium firm and would say that is right. So far so good and if run into problems in the future will come back to amend. So far very pleased.

Adequate for guest room. Too soft for me—I do like firm mattresses though. Convenient in the box. Shopping experience was awful though. Well—cashier was—rude!! And very strange—there was a music speaker on the floor that I almost tripped over. Playing loud music. I lowered the music and the cashier got aggressive about that. Just a strange experience.

Had this mattress now for about 3days. It’s exactly what it states itself to be as a “hotel premier” mattress. Now let me explain. Have you ever been to a hotel and the beds are really soft, whether through years of use or the type of mattress it is? Well this is exactly that. Can I get into bed and knock out? Yessir! However in my case, I wake up with super back pains. I typically sleep on a firm bed due to the back pain I have from an old injury. Don’t believe the line of “medium firm” it’s more like “cloud soft” so keep that in mind. My review is neutral due to me being able to just fall asleep instantly which is something I don’t normally do. If you want the fluff this is for you, if you want something rock hard then don’t count on this to be it.

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!

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. .

I bought this mattress after sleeping on a 1k Serta fancy all the bells and whistles and mattress for the last 5 years. I have never slept better in my life. It is a spiritual experience climbing into this bed every night. I have to fight off my children who try to climb in to our bed every night as well. It’s a neat lesson on physics too, during these homeschooling times.

2 months after purchasing this mattress it began to sag in the middle. 2 people sleeping in this bed wind up laying up against each other in the center of the mattress. THEN - since I can't read "fine" print - SAMS CLUB will not allow me to return the mattress because I threw away the box. THEY REQUIRE YOU TO BRING IT IN FOR THEIR 100% MONEY BACK GUARANTEE WITH THE ORIGINAL BOX. I am so disappointed in the mattress and SAMS CLUB. WHO KEEPS A BIG BOX STORED JUST EXPECTING A TRUSTED STORE LIKE SAMS WOULD SELL THEM SOMETHING CRAPPY THAT THEY WOULD NEED TO RETURN IN THE FIRST PLACE.
