Not as firm as I would like it. If you are looking for a bed that is stiff as a board, this isn’t the bed for you. It’s not bad, but not quite what I was looking for. It’s plushy with a firm feel. Overall, it’s not a bad mattress. I would have liked it to be firmer.

With mostly good reviews, my husband and I thought we would save some money and get a decent mattress from Sam's vs overpriced ones elsewhere. Man, were we wrong! When we first tried it out we thought "this is nice". It was softer than the medium-firm description. But the more you lay there, the deeper you sink. You get sweaty it's so hot. And uncomfortable. We had a crick in our neck the first few nights we slept in it (notice "in" it, not on it, because you are in this thing!"). You sink so low as your head stays on your pillow that your neck is in a very awkward position. We added a topper that helped some, but the mattress still sinks and sucks out topper in with it. It stinks right in the middle. We both wind up in the middle in this hole every morning. It's like a nest. A nest made by some gigantic bird that thinks we are its babies. If you like to sit up on your bed to watch TV or read, you can forget it with this one. Your bottom sinks in as you sit there and your little legs hang on to the top to keep you from getting completely devoured by the mattress. Reminds me of an old episode of "The Twilight Zone" or "Tales From the Crypt", I can't remember which one, but the bed was eating people. I really do not want to go through the hassle of trying to return this bed, especially because there is no way to get it back in the box. I don't live near by my Sam's Club either. On top of this mattress ordeal, they charged me twice for another item and can't take care of giving me a simple refund over the phone. They want me to drive sixty-six miles round trip to do that. I am very disappointed in customer service right now.

So I’ve only ever owned cheap spring mattresses they were way too firm and I’ve had back problems for as long as I can remember and I’m only 27. We got this mattress and I woke up so refreshed feeling. I need something that helps my pressure points and this did it! It does not sink me in but it curves to my body very lightly. I’m a side sleeper so this helped so much. I normally wake up with side pain and not anymore. Never woke in the middle of the night like I normally do. Both my kids have memory foam already but they’re twin mattresses so when we are ready to upgrade them I’d love to buy them the Members Mark one!! I never had any issues with a smell like the other reviewer and I only waited 24 hours it got up to 12 inches immediately but I still waited a day. Thank you Sam’s for selling an affordable comfortable mattress!

I love how it feel and I am able to sleep so well to the point I don't want to get out of bed. my body does not get any aches or pain laying on it and this mattress actual helps with me not sweating at night like I have done with other mattresses in the past. All in all it was a great investment for the price it was and my body/my sleep is all the better for it.

Ultimate comfort from a mattress that is delivered rolled up. I’ve purchased others, brand names, and nothing compares to this mattress. Priced right at about $200- for the twin size, I needed a mattress that would be on a platform without a box spring. This is the one, at 12 inches thick it has great comfort and support. You need to open it and let it air out from the factory smell, which only lasts about a day, also giving it time to fully expand. Great purchase, great quality, pleasant dreams!

I orginally purchased one of these beds with the adjustable base for my mother when she went into independent living. She absolutely loves it and my kids also love resting on grandma's bed. When we moved and my girls had outgrown their bunk beds, I bought two more. So, everyone loves their beds!

After getting an adjustable frame decided time to change mattress. Biggest problem was getting the old one off and ready for disposal and getting the plastic off the mattress was bit of challenge being careful not to cut the mattress. Once in place it began to hiss and start to expand quickly. Was surprised it only took a few hours to expand to 11 of its 12 inches! Very comfortable. Have seen reviews saying too soft but they must like sleeping on a rock as this is advertised as medium firm and would say that is right. So far so good and if run into problems in the future will come back to amend. So far very pleased.

This mattress is more comfortable than our temperpedic mattress that cost more than twice as much. I admit I was skeptical at first but the first time I laid down on it I was in heaven. We also purchased the adjustable frame and without a doubt they are a winning combination.

When we were looking at the matress selection at Sam's we couldn't find Soft type mattresses in store that would work with adjustable bed frame. We ended up on going with this medium firm Members Mark Hotel series and it turned out to be exactly what we wanted being that it's in a box and you can't try it out in store it actually was softer then what we pictured and for a side sleeper you feel nestled into the matress rather than on top and using pillows to get support its so nice what a difference it makes to sleep better.

Love the bed I own 2 a full and a queen the queen I had to get a replacement shortly after purchasing the zipper on the bottom of the cover did not zip came like that flipped over to try and zip but won’t work they replaced no questioned asked I’m really happy. They are not firm they say firm but they are quite soft you sink in them, i sleep every night in this bed I have no aches and pains it helps a lot.
