I was a bit spectical at first about buying a Sam's Club (Member's Mark) branded mattress at such a low price. I've always had a Sealy, Serta or a Sterns & Foster. I figured that it wouldn't be any good. But I read the reviews and decided to give it a try and boy am I glad I did! This mattress is AWESOME!!! I've had two spinal disc surgeries about 4 years ago and finding a comfortable mattress, with the right support, has been a challenge to say the least. I've been sleeping on a $2,000 Sterns & Foster for the past 4 years that was supposed to be "top of the line" in comfort, but even that mattress doesn't come anywhere close the true comfort of this one. I purchased the Queen size at about 10 in the morning and even though on the Sam's Club website it recommends that you allow the mattress a full 48 hours to conform to it's full size, mine was fully conformed in a matter of a few hours. I was able to sleep on it that same night. It was the first fully restful night's sleep I've gotten since my surgeries. It's nice and plush, but not so soft that you sink into the middle of it. It's got just the right amount of firmness for that much needed support. I've always been a hot sleeper and I found this mattress keeps me at a cool level of comfort all night long. I don't think I can say anything else about it other than it's just a really good mattress, and for the price, you just can't beat it!

I am extremely disappointed with the lack of free shipping for Plus members. It is unacceptable that despite paying for a Plus membership, this basic benefit is not provided. What exactly is the purpose of the Plus membership if it does not include essential perks like free shipping?

this mattress is terrible. only expands to 10 inches. when you sit or lay on it, it goes down to 2 inches. then when you want to return, they'll send a fedx truck to get it, but then , you are with out a bed. so to try and fix the problem, i brought a 4 inch pillow top. more money down the tube. in short, its junk

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.

Bought less than a year ago and is complete garbage. The matress already is sagging in the middle and if you lay to close to the edge you will roll right off because there is no structure to the edges of the mattress. Don't waste your money and can't return it because the store policy only covers the first 30 days. I would give it zero stars if I could.

This is a complete letdown. Bought a queen and two twins. All three of them have some weird bunched up sections on the tops. The twins expanded ok. The queen barely reached 10 1/2 inches. The sheets will not stay on at all because the bed is so thin and slippery. It is the most uncomfortable mattress ever. My body is in such pain. Dropped a load of money and disappointed.

So my partner and I originally purchased this one mattress in 2020. At the time, it was the most incredible mattress with great support- we couldn’t believe it was only $400. After owning it for two years we noticed the mattress wears down a lot quicker than what a mattress should and wanted to exchange it thinking it just may be a minor defect. Sam’s club was kind enough to exchange it for us behind their member mark lifetime warranty guarantee. When we got the new mattress we immediately could tell that it didn’t feel the same as the original one we purchased. We have it it a chance thinking it just needed a few days out of the box but unfortunately it just wasn’t the case.

Delivery from different locations took longer than initially projected. One box was overstuffed, as if it had been repackaged. After a few days they mattress was about 10.5 tall and 4 inches too wide at 42". They have been slept on 2 weeks and unpacked about a month. Still over 40" wide, making the 2 5-6 inches wider than a split king should be. Its risen a bot to almost 11", but still an inch short of 12" expected. It is plenty plush and not uncomfortable to sleep on but sheets and mattress pads were strained fitting over and likely why they measure narrower now. Not sure they'd stay compressed width wise with both off.

I bought a Nectar mattress at Sams Club and had to return it for a refund the following day. It was advertised as a Medium-Plush, but was so firm it was like sleeping on a cement slab. I had pain from pressure at several points on my body. I ended up buying this Member Mark memory foam mattress in the medium firmness, as there was not much to choose from at my club. Well, I can report that I am very happy I did. It feels so soft and comfortable, while at the same time being very supportive. I am comfortable on my back, sides, and stomach. No matter which sleep position I get into, I feel like I am sleeping on a cloud. I was pleasantly surprised I was able to get such a nice mattress for $400. It was $100 less than the Nectar and over $800 less than my previous mattress, which was not that good either. In fact, I had to use a memory foam mattress topper on it in order to use it. Thank you Sams Club for offering this great mattress!

We hated this ultra plus mattress. It's like molasses for the top 3 inches then hard as a brick underneath, which doesn't work for a side sleeper with hips. Returning this has been a NIGHTMARE, 3.5 weeks of Sam's telling me someone would contact me to pick it up. Finally I get a call from some company I've never heard of and I have to wait another week. They were supposed to pick it up but waited to contact me that day to ask for a picture of the mattress. They finally showed up in some random pickup the next day. It's been 2 days and I still haven't been credited for my return. I've been calling Sam's all day and they keep hanging up on me. I contacted the company that picked the mattress up and they say they emailed Sam's, but Sam's acts completely clueless. Now I'm still fighting to get my money back and I'm absolutely furious because Sam's had a junk removal company pick up the mattress. They'd rather send a brand new mattress to the landfill then let me donate it to charity. We are so done with Sam's, they suck.
