When we set it up it felt like we were laying on something hard, so I unzipped the cover only to find that they had put the mattress in upside down, and we were laying on the coils. I hope that's not what they do for all mattresses. We flipped it over, and rezipped it, and initially it felt comfortable, but by 2nd & 3rd day my lower back was killing me. We will be returning this. I would not recommend to anyone that could suffer back pain.

DO NOT BUY THIS MATTRESS! DO NOT BUY THIS MATTRESS! DO NOT BUY THIS MATTRESS! If the above warning doesn't convince you, I'll explain why. I bought this mattress to replace a Sealy I bought at Sam's over 11 years ago. The advertised features seemed convincing, and I liked the idea of it being a hybrid mattress because I'm not completely sold on all foam construction. I was also skeptical of a king size mattress being compressed into a relatively small box, but I reluctantly decided to buy it anyway. This ended up being one of the worst decisions I've made in my life. After bringing the mattress home and opening the box to allow it to expand, I was shocked to see that the mattress is folded and rolled under compression. I was thinking there's no way that the coils could not be compromised with this packing method, and I would soon realize that my assumption would be correct. 1. The first thing I noticed was the awful smell coming from the mattress, resembling something like mildew. The literature that came with the mattress noted that there would be a smell and that it would subside with time. This may be true, but it's not a good user experience for something that's claimed to be a premium product. 2. The next thing I noticed was the mattress not being squared (not 90 degrees at every corner). Some of the sides were even curved and would look bad if I had put bedding on it. 3. The foam top beneath the removable cover was not applied evenly with the other mattress layers. You can see in the attached pictures how the foam top has an overhang on one side of the bed. 4. The mattress looked wavy coming out of the box, but I gave adequate time to ensure it was not a problem with the expansion process. Sure enough, the waves never went away after 17 days without sleeping on the mattress. This is the number of days that passed before the attached pictures were taken. 5. The mattress is not true to size as other commenters have mentioned. It was at least 3" too short in some areas, less in others because of the cruved edges. 6. The worst part of all this is the lack of customer support from Sam's. I would not be able to return the mattress the same way I bought it from the store because it came compressed in the box, and I was told that I would have to return it to the store. This is now a huge inconvenience because I don't have a vehicle large enough to transport the mattress in its expanded state. I'll like have to rent a moving truck to finally be done with this poor excuse of a mattress being marketed as a premium product. I have enjoyed being a Sam's Club member, but this experience really has me thinking I should drop my membership and join their competitor that opened a location across the street. I am appalled by the lack of quality control on this mattress. There's no way that the manufacturer is held to any standard, and the worst part is that it's made in the USA, which is supposed to offer the best quality money can buy.

The mattress is great. More of a medium firm, but plenty of give and bounce being a hybrid with foam vs latex. Will update if after a few weeks there are any issues. Ships from the same factory as nectar and the other popular hybrid mattresses. FedEx has yet to deliver a single Sam's club order by the original estimated date. Ever. I would like an option to choose a different shipper.

The mattress was prefect at first but has seemed to lose its firmness in the 5 months I've had it. I purchased the medium but feels more like a soft at this point. Has anyone had this issue with theirs? Is the company willing to return the product for a firm in hopes that it will adjust to a Medium or stay firmer? I'm not a heavy person by any measure so the weight is not an issue.

mattress was lopsided, the latex pad was not centered on the springs. the cover was too big for the bed. i tried 2 beds with same results. Getting sams to pick up the beds was nor a pleasant experience. i would not recommend this bed. i dont understand why this bed was given great test result on a leading reporting service.

Ordered King Medium. This was my first hybrid bed in a box. I have had the mattress for 6ish months... i am a side sleeper. Female, 53, 165 pounds and 5'4. At first it was good...but now my hips and lower back are hurting me. BTW I take Aleve at night too. The mattress has nothing wrong with it...no sag or indent. Just not working for side sleeping.

Wow! I was super worried about purchasing a bed online without trying it out. I have to say this is a great bed. we bought the firm version and it is perfect. It has all the features of a bed 30-40% more expensive. The firm bed is perfect for me (side sleeper, 200lbs, 6'5) The part that really sold me is Sam's return policy. They let you return at any time with no restrictions. I didn't return the bed because it was perfect, but I felt sure with my purchase!

If you are looking for a true firm mattress this is not the mattress for you. We’re purchased other memory foam mattresses from Sam’s and have always been very pleased. When it was time for a new mattress I was skeptical of the hybrid mattress but decided to give it a try since one of the options was “firm”. After letting the mattress expand to its full size I was initially pleased with the overall thickness of the mattress. Then I slept on it. I have always had a firm mattress. I would rate this version of this mattress as soft. I verified that my receipt and the box I received all stated that I ordered and received a firm mattress. Unfortunately this will likely wind up being a complete waste of my money and will likely end up in a landfill sooner than expected.

Avoid at all costs. Mattress started to break down within weeks. And now I am dealing with customer service and that is a useless and extremely exhausting experience. Return started on 2-9 and it is 2-20 and I am still waiting for a call from the carrier. Have called Sam's Club 5 times now and each time am told ATI will contact you in 24 to 72 hours. Do not buy a mattress from Sam's. Quality is garbage and customer service is even worse!!!!

Where do I even begin with the Member's Mark Hotel Premier 14" Hybrid Mattress? Let me start by saying the word "Premier" is doing some very heavy lifting in that product name — unlike the mattress itself, which can't even support a small child without swallowing them whole like some kind of foam-padded Venus flytrap. I've slept on air mattresses at 2 a.m. after Thanksgiving dinner that offered more structural integrity than this thing. Calling it a "hybrid" is generous — it's a hybrid of disappointment and regret. Fourteen inches of mattress and somehow every single one of them is useless. My kid sits on it and practically disappears into the abyss like it's a memory foam black hole. The only thing this mattress is firm enough to support is my growing resentment toward Sam's Club. Speaking of which — let's talk about that famous "Satisfaction Guarantee." You know, the one proudly plastered across their website and membership materials? Turns out it comes with a silent asterisk that reads: unless it's this mattress, in which case, good luck and may God have mercy on your spine. I tried to return it and was met with more resistance than the mattress has ever provided my back. Apparently "100% Satisfaction Guarantee" is more of a vibe than an actual policy. So here I am, stuck with a $400 slab of lies, sleeping like I'm suspended over a pit of marshmallows, wondering what I did to deserve this. If you're looking for a mattress that functions as a mattress, keep scrolling. If you're looking for an oversized, overpriced dog bed that will also teach you a valuable lesson about reading the fine print — this is your guy. Would not recommend to my worst enemy. Would recommend to my neighbor who keeps parking in my spot.
