astronomical mattresses. Definitely choose this one over the new hybrid one. My entire household has these in all sizes. I bought my first one about 5 years ago and it hasn't had any impressions or imperfections. highly recommended. It has significantly reduced my lower back and hip pains. even the dogs love it

I have had this mattress for a month and so far I really like it. It had a slight odor upon opening but I left the fan on as it fluffed up and the smell went away fairly quickly. It was not bothersome at all. I was used to a very firm mattress so this one was an adjustment but I actually like this one much better than any others I have tried. It is soft enough on top and firm enough underneath for good support. I have been sleeping better on this mattress than others I have tried or bought in the past. It is very reasonably priced and I am very happy with it. I highly recommend.

Bought less than a year ago and is complete garbage. The matress already is sagging in the middle and if you lay to close to the edge you will roll right off because there is no structure to the edges of the mattress. Don't waste your money and can't return it because the store policy only covers the first 30 days. I would give it zero stars if I could.

I had a 5k high end name brand mattress I’d been sleeping on for years and then for the last few months I found I could not get comfortable on it no matter how I turned. I had slept on a full size of this mattress while recuperating from hip surgery and had found it extremely comfortable! So I decided to replace my expensive mattress for this one. Extremely smart decision! It is so comfortable! I do not have to constantly reposition.

Defective-as others have stated, it has a lump in the middle. Bought it for my guest room. Contacted Sam's through chat to find how to complete a return. They just said I needed to talk to the store. Store said I could put it back in the box (which is impossible) or wrap it in plastic. Then I get to stuff it into my car (which it won't fit in) and drive it back. I also don't live near Sam's so this whole thing is incredibly inconvenient. I tried to upload a picture, but this app only gives me an error message.

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.

I know this mattress is an inexpensive mattress, but I believe the top layer of the mattress should not have stretched/separated to the point that it causes pain. I am older and have no way of returning it fully expanded. Note: The bed was a dream the first week and I slept better than I had in a very long time. I was absolutely delighted, but my euphoria is rested and low pain was short lived. This mattress should not be advertised as being compatible with the adjustable base. The base was purchased from Sam's Club as well.

So far, it's great 👍 The mattress puffed up quickly right out of the plastic wrap. It might take a few days for my dad to get accustomed to the memory foam, but its better than the cheap mattress from those firm stores at every corner of town. I wish Sam's also sold a base or bunky board.

I bought this bed because my Orthopedic Mattress was beginning to get too hard for my older body. I had sore shoulders and back. This was delivered to the door in a large box. It's bulky but manageable, I am 65 years old and managed to move to the first floor. Once unpacked it rapidly began to expand. I let it expand for 24 hours. It appears to be about half to one inch short of the 12 inches advertised. I have no experience with foam mattresses so didn't know what to expect from Medium Firm. Turns out it works well. My stiffness is slowly dissipating though it took me a couple of nights to get used to sleeping on a foam mattress. I didn't get the chemical smell some reviewers noted, I still have a pretty sharp sense of smell. After about a week I am pleased with the mattress. It's hard to beat the value of the Members Mark and return guarantee. I took one star off for the actual height being shorter than advertised.

Purchased two queen mattress’s guest bedrooms. Everyone remarked how well they slept on them! Arrived pretty quickly after ordered. Arrived in a large but not too bulky box. The mattress expands after unboxing. Not two heavy but does take two to maneuver due to size.
