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

Terrible product and impossible return

Defective-as others have stated, it has a lump in the middle. Bought it for my guest room. Contacted Sam's through chat to find how to complete a return. They just said I needed to talk to the store. Store said I could put it back in the box (which is impossible) or wrap it in plastic. Then I get to stuff it into my car (which it won't fit in) and drive it back. I also don't live near Sam's so this whole thing is incredibly inconvenient. I tried to upload a picture, but this app only gives me an error message.

Measurements off not Twin XL sized

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.

One of the best mattress I have ever had, period.

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!

NOT firm at all!

Bought this for the reviews, it is NOT FIRM at all. Actually going to return it. Not sure on the great reviews. If you want soft and squishy and back breaking go for it. NOT FIRM, returning it due to so soft I am crippled. I ordered firm for a reason and this is not it.

good enough but remain to be tested

Better than expected. I did NOT like memory form mattress because I prefer firmer mattress with steadily support. I hate the endless sinking feeling that my husband's old memory form had as well as others I have tried. But this memory form mattress from Sam's does not give me that sinking, unstable, wobble feeling when in bed. I choose firm and to me it's medium. But good enough. I think firm is ideal for face-up sleepers but less ideal for side sleepers. The remaining question is how long can it stay in shape without becoming too soft or even collapsing.

Very disappointed.

Bought this mattress on 02/06/2023. It is now 3 years old and it is junk. A year ago it started to bunch up in places, and now sags with no support. From the sounds of others comments, no point in trying to get warranty service. Both my wife and I now have back problems.

Exceeded my expectations!

I was in a financial and time crunch. I recently moved and had to purchase a matress quickly. Admittedly, I turned my nose up, assuming the store brand would not be comparable to the major matress brands. Bae-be was I wrong, wrong-wrong. This bed is firm like I like and applies the perfect amount of pressure to my lower back.

Medium feels like ultra plush

The reviews about it being too soft are correct. I have another memory foam mattress. Different brand. That is plush and isn't nearly as soft as this medium. It feels like you went to sleep on an air mattress and woke up in the middle of the night and it was flat. This is excessive. I like plush. But this is next level. It almost has me wondering if they put the wrong one in the box

Worked in a jam. Picked up a mattress on the cheap after ours was ripped my movers. I also picked up 2 twin xl for 2 of my kids after they got new beds. I shoukd have known better for our adult bed. It was comfortable for a little over a year, then had noticeable dips and sag in the top layer. My partner and I both weigh between 140-150, so we aren't overly large people. Rotating the mattress didn't help prevent the sag. After 1.5 years my back couldn't take it anymore, and this mattress had to go. I'm also noticing a bit of sag in the 8 year old's mattress. She's under 100lbs AND doesn't live with us/sleep here full time. The top layer just doesn't hold up. No issues on the mattress for the 4yr old but... she's 4. Same thing there - that she doesn't sleep over at our place every night. Wishing I had just gotten innerspring mattresses for the kids, and gone back to our original mattress (Tuft and Needle) from the get go.
