love the mattress but 4 stars because the cover is so slick we actually removed it to get the sheets to stay on. sams find a less slippery cover! i would buy again knowing i would be replacing the cover instead of trying to make it work as is. still very affordable.

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.

The plush mattress is like sleeping on a marshmallow. You totally sink into it. No support whatsoever. And I like a softer mattress. But not this. Also, there is NO reason for it to be 14 inches thick. Making the bed is a nightmare and keeping some expensive deep pocket sheets on it is impossible. Have had the mattress on a guest bed just a few months. Will be putting on the curb for garbage pickup soon.

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.

We bought two MM 14” medium-feel hybrid mattresses, and we could not be happier with our purchase. We sleep supported—without sinking in—and cool. And we rest for a minimum of 5-6 hours before awakening. Then it's back to sleep. These are the best mattresses we have ever owned, and they are competing against high-end, ripoff-priced mattresses that we owned previously and that cost $6,000 and $7,500 (specialty brands from San Francisco). If you need a mattress, don't delay. Members Mark will save the day.

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!!!!

I've been trying to buy a mattress for 3 years. I've bought memory foam and I hate it due to it making my hips hurt and I sink so far down into the bed I have to climb out. I thought this would be a good choice as it's hybrid. No. I got it in a box all rolled up. Opened it and let it expand. I bought the ultra plush thinking it would be perfect. It has a zip cover on it and there was tons of slack like it was missing 1/4 of the mattress. The springs were sticking out really bad. I slept on it two nights and it caused horrendous back pain. I happened to have another 3inch memory foam mattress from a camper van I sold. I forced that mattress into the zip cover and I have salvaged it. No way was I going to try to return this as I would have probably had to haul it over an hour to my nearest Sam's Club. But it was NOT worth the over 400$ I spent on it. I do not recommend.

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.

It said is medium but is really sof

Not as firm as I was expecting. I ordered the firm but the mattress is more like a medium firmness.
