We have 2 queens of this mattress and love them. We tried a queen first before buying a king size. Have been really disappointed in the king. The king size mattress is so soft and already has dents after 4 weeks of use. We used the queen for 8 months and didn’t have any of the issues we’re having with the king.

Purchased for the guest room. I didn't use it myself, but a visiting family member was comfortable and slept well. It's a very thick mattress, so if you use it with a box and a standard bed frame it would be pretty high. I used it with a fold up metal bed frame and a thin mattress pad under it, no box and it was high. Set up was easy for the twin size. I was able to do it alone. The mattress fluffed up fully in a few seconds. I didn't notice any offensive odors, but it wouldn't hurt to let it air out a little before putting the sheets on to let the new foam bed smell dissipate.

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.

Bed is really comfortable unfortunately it was deformed. Like other reviews, the end of the bed failed to to inflate to full capacity. Looks odd and also the top moves around when getting up. I’m contemplating returning but this would be the second bed in a box I return. Not sure it’s worth the hassle.

I have purchased the Serta mattress at sams and the quality is way different. This mattress is very weak around the edges and the corners are worse. If you are using a platform bed that is slatted the mattress will push right through so you will need some kind of support between your mattress and the slots. I would recommend the serta bed in a box over this one for sure.

I have purchased 4 of these over the last 2- 3 years and will continue to purchase them. I had my doubts based on the price point, but I was pleasantly surprised. I originally bought them for me kids and they liked them. I recently purchased one for my guest room and have slept on it the last 2 nights. I realize that I need to replace my own mattress after only 4 years because I slept so well on this one!

Mattress is far too soft you will end up with severe neck pains. The mattress has completely compressed and now I am experiencing both neck and back pains. This all even though I didn't sit or sleep on it for 72 hrs. after opening. This scenario is absolutely absurd and very disappointing

After reading the negative and positive reviews for this mattress, I decided to give it a shot because we were in desperate need of a replacement. This mattress is advertised as a medium-firm mattress, but it is NOT that whatsoever. This mattress is SOFT... so soft that your entire body will sink in if you weigh over 150lbs. If you’re into that, then it may work for you. But if you bought a medium-firm mattress because you prefer medium-firm mattresses, you will be highly disappointed. If you prefer firm mattresses and thought you might just settle for a “medium-firm”, then you may fall into a deep depression. Believe me before you waste your money like I did... this mattress is nowhere near medium firm, or even medium. Also, prepare to have your room smell like chemicals for several days. We off-gassed and decompressed this thing for an entire day outside and the smell is still giving me headaches. Here’s to hoping I can return this thing!

We hated this ultra plus mattress. It's like molasses for the top 3 inches then hard as a brick underneath, which doesn't work for a side sleeper with hips. Returning this has been a NIGHTMARE, 3.5 weeks of Sam's telling me someone would contact me to pick it up. Finally I get a call from some company I've never heard of and I have to wait another week. They were supposed to pick it up but waited to contact me that day to ask for a picture of the mattress. They finally showed up in some random pickup the next day. It's been 2 days and I still haven't been credited for my return. I've been calling Sam's all day and they keep hanging up on me. I contacted the company that picked the mattress up and they say they emailed Sam's, but Sam's acts completely clueless. Now I'm still fighting to get my money back and I'm absolutely furious because Sam's had a junk removal company pick up the mattress. They'd rather send a brand new mattress to the landfill then let me donate it to charity. We are so done with Sam's, they suck.

Mattress is super comfy. I am 5foot 8 175 pounds and it is a perfect mid support mattress. I am a side sleeper and if the mattress is to soft or hard I wind up with back pain. I have had no pain with this mattress. It would be a 5 star but the workmanship on the mattress leaves a little to be desired. The cover you can tell was accidentally glued to the mattress in some spots causing the mattress to not rise completely. Also the cover is a little to large for the mattress making it too loose for the mattress. Like any foam mattress it smells awful for about a day or two till the smell goes away. If they can get the quality up just a little on the build it would be a 5 star
