Overall the mattress is nice and comfortable, however it is not a true king size mattress. The specs on the website list it as being 76x80, but it is only 77" long. When I put it in the bed frame I noticed a large gap at each end compared to our old mattress. My feet hang off the end. I guess that's how they offer the Sam's discount by removing 3 inches from every mattress.

I love this bed! I was weary about buying a bed in a bag but decided to give it a whirl. I will never look back about buying a mattress from a bed store. I am pleasantly surprised with how easy and efficient it was to put up. I was able to sleep on it the same night, but it continued to firm up for the next 3 days or so. I bought the firm for my room while my husband bought the medium for his room. I had back surgery about 2 years ago and my old mattress was 11 years old. This is my first time buying a firm bed. Now, the firmness will be a perceived feeling, but it is like a hotel mattress. It conforms to the body but doesn’t sink in. It is perfect for me and supports my back and hips perfectly. The medium also feels supportive but it conforms a bit more to the body and has a bit more give in the mattress. I have no aches or pains on either bed but the firm is more supportive for me and better on my joints. My husband prefers the medium but likes the firm, too. It really is just a matter of preference. Overall, medium is a perfect bed but the firm is more supportive for my condition. I’m very pleased with my purchase

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.

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.

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.

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.

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!

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!!!!
