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.

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.

This is our 3rd mattress in 4 months. Finally a winner! I am 130 lbs and no back or other issues. We first purchased the Nectar Premier mattress it was to soft. I had a backache from day 1 that never went away even during the day. Then we purchased a Serta perfect sleeper firm mattress. My back ache went away, but it was very hard. My shoulders hurt sleeping on my side. Absolutely no give at all in that mattress. Decided to take a chance and purchase this Sams Hotel Premier Hybrid medium mattress at Sam's Club. It's perfect! It is definitely comparable to a high-end mattress. Very comfortable and supportive without being to soft or firm. It does seem very cool to sleep on which was also important to us. My only negative which is minor to me is it should be 14 inches high but mine measures 13 inches. Hope it holds up for years.

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.

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.

Liked the price slept great for 2 days. The the pain started gradually getting worse 6 weeks in rib pain lower back pain so bad 2 trips to doctor for exrays chiropractor many times. Could be I'm older or wrong firmness or just not for me. Its weird seems soft and hard make it make sense. None the less its going back never hurt this bad on cheap spring matresses maybe my body is like dude you waited to long ive slept on some pretty rough stuff but never had rib pain like this my god never anther hybrid ugh.

This mattress is wonderful!! First good night of sleep in months. We both woke up rested with no back or knee pain. Should have gotten this a long time ago. Came well packaged. If you need to get some excellent sleep. You have to try this mattress - you will not be disappointed.

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!!!!

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.

Would have rated the king size hybrid mattress a 5 star except 1) It has a "cigarettes smoke" like odor for a month or so once it is taken out of the plastic wrapping 2) The sheets easily slide off due to the mattress being compressed when laying on it. Otherwise I love it!!!
