I can't speak to the long-term reliability of this mattress yet because we've only had them about a week. But i bought 3 of the twins for my kids 2 sets of bunk beds with trundles. I had 3 innerspring mattresses and needed 3 more and this is what I could afford and I had worried the kids would fight over the traditional thick mattresses and not want to sleep on the thin "cheapies". However , the opposite is true.. all 6 kids from 7 to 17 wanted the memory foam mattresses and say they're extremely comfortable and soft. Looks like I'll have to buy 3 more. My only complaints are that they're a little flat on the corners and they're more like 7.5" instead of 8" but for the price they're great beds and the kids love them.

This Zinus Night Therapy Memory Foam mattress is like sleeping on clouds. Very comfortable. I bought this for my 18 year old son and he said "mom this mattress is AMAZING". He is very happy with it. Now its even harder to get him out of bed. I'm very glad I purchased this mattress.

I have never had a memory foam mattress before. Initially upon sitting on it, I didn't like it. I went from a medium firm expensive mattress that was about 12" to this one. It is 4" shorter so I am lower down (I'm short anyway) and the other was a traditional type mattress. I have to say, after trying it for a few night, so far I like it.

My husband and I bought this mattress to replace the one in the camper we just bought which was hard and uncomfortable. I bought the queen size which fit perfectly and is very comfortable. It was easy to get it in the camper since it comes in a roll. Also the sheets fit perfectly.

Bought this mattress for our RV. My husband has issues with his arms going numb every day after sleeping on our sleep number bed. We went on a trip in our RV last week, and he had no issues with any pressure pain, and slept through the night. I found the bed very comfortable, and a great find for the price! Thinking about replacing our home sleep number bed with one of these.

Received the mattress, let it expand, and it completely dips! We sink in towards the center when we lay on it. We took a nap on it, and my back hurts from trying not to roll towards the middle- similar to an air mattress. I didn’t know memory foam could even do that?! How in the world would I even send it back?! We’ve had several memory foam mattresses and never had this happen. It’s fine otherwise. Can I get a replacement? Not even sure how that works!

By far Best Deal For The Money!!! I got this twin size mattress for my son. I have not slept in the bed but I have asked him and he tells me that it is very comfortable. What I liked the most was the price! If it was any higher I would have gotten with a different mattress. Thanks.

We purchased these for our two teenage boys and they are amazing! Anyone considering purchasing this mattress should! I was leery at first because the price seemed to good to believe but when they got here I was so pleased! This was absolutely one of the best purchases I have ever made from Sams!

My son needed a new mattress. I searched online and in many stores for affordable options. Some did come in slightly lower than this mattress, but they were half as thick, or not memory foam at all. I wanted him to have a nice memory foam mattress that could last through middle school and high school. NOTHING this nice was offered at this price anywhere else. When it arrived, I let it expand on the living room floor. My husband asked how it felt, so I went to try it in order to report to him at work if it was worth the purchase. I have trouble sleeping. He arrived home to me passed out for four hours in the living room on this twin mattress. No smell from the foam, expanded within 5 minutes, best mattress I had ever slept on till the 12" version of this came the next day for our bed. This mattress is not as extremely firm as the 12" pressure relief version we chose, which makes it perfect for our 11-year-old son. I would recommend this mattress to anyone who would not like the firmer option but dislikes the sinking into a pile of squish that the softer mattresses offer. It is a nice Goldilocks balance.

I bought this mattress for use in my motorhome. I have a top manufacture brand memory foam mattress that I sleep on at home every night. I decided to save some money and buy this much less expensive brand. After sleeping on this mattress for the last week while on a camping trip - I have to say that the comfort level is almost equal to that of the top brand. The only difference is I think this brand retains more heat than the one I have at home. If you're looking for comfort at an affordable price (and don't mind being warm), this is a great mattress. Sweet dreams!
