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.

I researched for over a month before purchasing. BEST PURCHASE EVER! I was waking several times a night hurting in my hips and lower back on my Temperpedic mattress. From night one on this Members Mark hybrid, I did not wake up once hurting. I even slept an extra two hours! This purchase is well worth the money.

Wife and I bought the Medium version of this in store. This mattress feels like a plush and you sink in pretty deep while sitting. It is comfy while laying but a little to soft for us. We ended up ordering the Firm version online the next day. Will be returingin the Medium version once the other comes. Hopefully the Firm will serve us better.

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.

I got this to replace a mattress that cost about 3x this price of this one. I was leery to order something I hadn't laid on but read that Sam's has an awesome return policy, so it felt low risk. It arrived within a couple days. I was nervous that a mattress with springs would be rolled up in a box. However, once I cut the plastic off, the mattress decompressed and seemed full height within minutes. I did smell a slight chemical off gassing the first night, but not after that. I am really pleasantly surprised with this mattress... compared to my expensive one, which was also a hybrid, it is just as comfortable, has the perfect amount of give with the memory foam, but the support of the spring base. I got the medium. I have been sleeping great. I am a side and back sleeper. It has not seemed to sleep hot at all... if anything, it feels a little cooler. I would say the sides are maybe not as reinforced as my $$ mattress, but that's not a big deal to me, as I don't sit on the side of my bed for anything. I am waking up with ZERO back and hip pain, which is why I replaced my mattress to begin with. I was having SI join pain, tightness all down my legs and even in my obliques (I am a fit 45 year old female, 5'3" 120 lbs). I was beginning to think it was just some aging aches and pains, but am just so relieved to have zero pain now!

complete waste of money. save yourself the hassel and just spend more and get a nice mattress.

We were skeptical but so far we have been impressed with the mattress.

Purchased the KS Firm and couldnt be happier. It molds perfectly to your body and offers excellent support. Cooling layer is really effective. I was worried about the memory foam being too hot for me but I really didnt need to worry at all. I will certainly be buying these for my other beds.

I would not recommend this mattress. It was shipped in oblong box torn and tossed. No label of top or bottom of mattress all wrapped in an abundance of thick tight plastic. Very heavy oblong cardboard box and rolled so much it was giving away and becoming rounded. Very difficult for 3 people to pick up and move. FEDX had difficulty also. The mattress has NO springs in the side edges of the mattress where you would sit on the side of the bed. If it does you cannot feel them and they do not support you. There are coils and springs in bottom of mattress where your footboard is at. These coils and springs are lumpy bowed out and hard bowed buldged on the side of the cloth of mattress. The mattress itself took much work to get it open out and placed on the bed. It smells like high amount of paint or chemicals has been poured into the room where it on the bed at. This is day 2 and the smell with a fan on and the windows open is overwhelming and cannot be good for you at all. This mattress soft touch and the material top covers are beautiful. The material and the quality of this mattress is wasted money. I would never recommend it to anyone. The struggle of it all and the quality that you paid for is NOT worth it. I am very disappointed and referred others to be members of Sams. This mattress is not Sams Members quality at all. To send back or take back this mattress is out of the question. I would have to buy box and No Way you can roll this mattress back up. Get 3 or more men to get it out of my home and then carry in what a trailer back to the store or Van. Very disappointed to say the least. Home smell is not worth your time for this mattress either. I will never buy another rolled up mattress in a box.

Purchased the medium and it is as to be expected for a bed in a box. However, the mattress is 6" smaller than a standard King sized mattress. Therefore, it does not fit correctly on the bed frame. Which is highly disappointing since the closest place to return is 100 mile drive.
