A total piece of crap!!!

I bought the full size mattress on sale and it's already developed rises in the middle of the mattress, it's one inch wider than my bed frame and instead of the supposed 12 inches , mine only came up to 10 inches…in short a total piece of worthless crap!!!

Great high quality mattress!

The bed came well packaged and very securely wrapped. As soon as I opened the packaging it completely sprung into shape with no issue. We're waiting a full 24 hours before laying on it. We ordered the medium and it's plenty soft and plush. I think it's perfect for my daughter but for me personally I would use the firm.

Poor Craftmanship

I bought this mattress in May of 2025. My grandchildren came and stayed a week in Oct of 2025. I have enclosed pictures of what the mattress looked like after that week, I could not iron the bumps down, I could not smooth the bumps down and they showed when the bed was made up. Look really tacky. I was shocked and surprised as Sam's products are usually some of the best. I always shop Sam's before going somewhere else. Sam's did send a pickup company to get the mattress and I did not have to take it to the store.

Size does Matter

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.

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.

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.

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.

Comfortable Mattress

Our daughter graduated from college and moved out so we gave her all the furniture in her room. We were going to buy an air mattress for temporary use for guests but decided to get this mattress for them during the holidays. Everyone who slept on it commented on how comfortable it is. Definitely a good purchase and can now become permanent for guests visiting over the next few years.

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.

Nice bed

Nice bed not as good of quality as the one I bought in this brand 4 years ago but still nice just. was wishing it was the same. It’s a little softer than the previous. Only perched a new one because wanted a bigger bed had a queen and just bought the king. Would still highly recommend. Just wanted to let everyone know it is quite a bit softer.
