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.

1 year review of the medium mattress by a 230lb side sleeper: Month 1: Foam was is so thick, its cloud like. Felt more like a plush than a medium. Months 2-3: Perfect. Slept great. Months 4-5: Noticing the foam layers are beginning to lose their loft. Month 6: Foam is starting to bottom out, I began to feel the coil spring layer on my side. Months 8-9: Mattress foam was no longer providing any support. I felt as if i was sleeping on a firm coil spring bed. I began thinking I'm going to need a new mattress soon.. 12 months: Mattress has been replaced and now in the towns dump where it belongs. I had high hopes for this mattress but the long term just isn't there.

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.

If you are looking for a true firm mattress this is not the mattress for you. We’re purchased other memory foam mattresses from Sam’s and have always been very pleased. When it was time for a new mattress I was skeptical of the hybrid mattress but decided to give it a try since one of the options was “firm”. After letting the mattress expand to its full size I was initially pleased with the overall thickness of the mattress. Then I slept on it. I have always had a firm mattress. I would rate this version of this mattress as soft. I verified that my receipt and the box I received all stated that I ordered and received a firm mattress. Unfortunately this will likely wind up being a complete waste of my money and will likely end up in a landfill sooner than expected.

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!

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

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.

Very comfortable

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.
