Sams keeps deleting my reviews! Recieved a used mattress with head stain, butt dip, and flattened side. Was in an unmarked box and clear bag that was shrink wrapped Now have to rebox which is impossible to return via fedex, or gl to sams club store to return a 125# mattress.

Maybe it’s just me or I got a bad mattress, but this mattress was pretty hard. I could only sleep in it a couple nights and my back hurt like heck in the morning. My son has a memory foam mattress classified as medium support from another maker and I love his. Thankful Sam’s gave me a refund. I will donate this mattress and go look for another one.

Not sure why other people have had size issues but this mattress DEF expanded after several hours to 12". We did lay it flat on the low profile box spring and didn't sleep on it for a day. And another person saying the cover couldn't be removed to be washed is wrong...there's clearly a zipper for removing the cover on the bottom of the mattress. It doesn't get easier to buy than this...box has handholds and wheels so you just pull it to your truck or SUV and load 'er in! Slept great on it and for the $, it can't be beat. Sure, I had a $2700 Temperpedic full foam in past....but it was warm and while I dont sink as deep in this Serta as I did in the Temper, I didn't notice while sleeping or waking without any aches. SO...money saved and value received.

This is the first review I've ever left but I think it's important and hopefully it will prevent someone else from having problems. I bought this mattress due to back issues. It started out great-for a few weeks. Within the first month it got a very large dip where I sleep that is so bad you can see it when the bed is made. After two months I rotated the mattress and now there is a dip in the new spot. For reference, I weigh 120 pounds. My back is worse than before I got the new mattress. I have only had this mattress for a few months. I have much less expensive memory foam mattresses that I purchased for my children from another company that have held their shape for over 5 years and are clearly higher quality products. This mattress is terrible. I regret ever buying it.

Had the bed for over a month and agree with the person that said it was fine for heavier people. I'm not sure if the guy that said he was 240 lbs was reviewing the correct mattress, but I'm closer to 300 lbs and there is very limited sinking and turning over is not a problem. Consumer Reports rates this mattress very high even among spring/foam fusions and the more expensive $1000-2000 beds. They even rate it a 7 out of 10 in firmness, which I agree with. If you are looking for something similar to laying on concrete, then maybe this isn't for you, but if you want something with mid-high firmness, you'll be more than happy with it.

I have the Serta 14 inch king size for our master bedroom and I love that mattress. Decided to buy the 12 inch for our gest bedroom queen size. Was at the club pickup up one of the boxes went home opend the box and the cover was ripped. I could see the damage of the cover through the plastic. Took the mattress back at the store returned it and picked another box. Opened the other box home and waited for the mattress to expand. It expanded only to less than 10 inches and the cover is loose. For the price this is not acceptable. Will start the return process. If I wanted a 10 inch mattress, I would have bought a 10 inch mattress which also cost less.

This was a big disappointment because it was way too soft for medium size people. Did not help with back pain like my 17 year old memory foam mattress that I loved. Top foam too thick, felt like I was drowning in bed. Worst was the foam did not recover from body impressions. Had dips that showed badly, so I'm returning it to Sam's. The mattress cover is nice however, if that means anything.

i have bought 4 of these mattresses, or at least i tried to. the first one i bought was a king and queen. after hearing amazing reviews i figured i’d give them a chance and after unboxing them and waiting the 48 hours they didn’t blow up all the way and they weren’t comfortable. after being sad about it a month later, a friend told me they got another and it was great. silly me, i decided to give it another shot and i got a full sized since i wouldn’t be sleeping on it regularly. this one actually did inflate but there was a tear on the side of it that i didn’t notice for about a week. i’ve heard so many great things about these mattresses so it was sad to have this happen. lastly, i got one more which was for a family friends birthday present because, against what i said, she wanted to try it out. and no surprise, it didn’t inflate. my fault for believing in the company but i wouldn’t recommend them. luckily, sams club refunded me for the mattresses and we just discarded them ourselves. i wouldn’t recommend these boxed mattresses.

I read reviews & research ALOT before buying major purchases ESP a large one &/or one I'll be using a long time. I did both with this mattress including CR but still a little skeptical bc I didn't get to lay on it. Even checked out reg box springs/mattresses because that's what I'm used to but I NEEDED relief from the aches and pains associated with sleeping. This purchase was and is everything I wanted and needed! It's comfortable but most importantly my BACK or legs or neck don't kill in the morning anymore! Equally important is the cost is a fraction of what traditional mattresses cost! Re: S/H received pretty quickly, so much so I wasn't quite ready for it. I had bought a Zinus quick snap standing mattress foundation but the model I bought was a little too low to store tubs under (a must have for my space) so had to figure out how to heighten it. Once I did and the foundation was in place, the easy task of opening the box and cutting loose took place. The only "complaint" I'd have is I wasn't sure on the mattress which side was supposed to be up (or down) so went strictly by the picture (I need everything laid out for me!). Anyway, I'm sure you'll love this as much as I do and love the savings as well!

I bought this mattress less than 2 weeks ago and have already returned it. It was extremely firm, like sleeping on the floor. It never expanded to 12 inches, 9 1/2 at best. Unzipped the mattress cover and it was 2 layers and not 3. Would not recommend this product at all.
