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.

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.

Wow! I was super worried about purchasing a bed online without trying it out. I have to say this is a great bed. we bought the firm version and it is perfect. It has all the features of a bed 30-40% more expensive. The firm bed is perfect for me (side sleeper, 200lbs, 6'5) The part that really sold me is Sam's return policy. They let you return at any time with no restrictions. I didn't return the bed because it was perfect, but I felt sure with my purchase!

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!!!!

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.

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

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.

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 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.
