This is a great mattress if you are a side, or back sleeper. We went with the Medium and it is more on the firm side which is what we were hoping for. Other reviews seem to describe this so that is how we made our decision. This is very supportive and supportive right to the edge of the mattress. This does not seem to get that warm and we did end up putting a mattress topper on it since my wife like a softer top. It really did not change much in my opinion since they just squish down to the actual mattress. Yes I would recommend this. I am 59 and a hard worker with the normal aches and pains that come with hard working and I definitely get a good nights sleep.

We ordered 2 Twin XL mattresses. Boxes claim to be Twin XLs but when we opened the boxes and allowed the mattresses to expand they measure as a regular Twin size mattress, 5 inches shorter than a Twin XL. All tags on the mattresses claim to be Twin XL.

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.

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.

This mattress killed my back. Was way too soft (I ordered the medium) and had to return before having it a week. The online return process has been a nightmare! It took 3 weeks for someone to pick it up and they said it will be another 2 weeks before I may possibly see my refund. I will never buy another large item online from Sam's Club again.

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

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

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.

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.
