Review: Two Years of Cool, Comfortable Sleep in Our RV – No Regrets - Two Years of Cool, Comfortable Sleep in Our RV – No Regrets We've slept on this Dynasty CoolBreeze gel memory foam mattress in our RV for two full seasons, and it still feels supportive and temperature-regulated. The 10" profile fits our short king frame perfectly, and the gel-infused foam noticeably reduces heat buildup compared to standard memory foam—crucial for desert camping. Pressure relief is solid for side and back sleeping, and motion isolation means we don’t disturb each other. The washable cover has held up well through regular cleaning. Only note: edge support is a bit softer than we’d like when sitting on the side, but it hasn’t affected sleep quality. For RV-specific sizing and genuine cooling performance, it’s been a worthwhile upgrade.
Review: The most comfortable mattress I have ever owned - I did a lot of research to find the best mattress for my RV. I live in my RV full time so I wanted a mattress that would be comfortable but also hold up over time. I read tons of reviews on several mattresses and I visited many stores and websites looking for a good but affordable mattress. I read the reviews for this mattress so I kept coming back to this choice. This mattress is firm but it's soft at the same time. It's not hard but it's not soft enough to sink down into. It's just perfect. It sounds kind of silly but my both my husband and I, when we settle in to bed, will say, "I just love this bed" and we say it at least once a week, if not more. We try to stay conscientious of being grateful for all things and this mattress reminds us every night of how grateful we are of a comfortable bed and good sleep. I had no problems with the delivery of the package. Not even a tear on the box. The mattress was covered and sealed. Everything was clean and I didn't notice any smell. I've slept on this mattress every night for over 2 years and even in Winter and sub zero temperatures, this mattress is still just as comfortable. It's been worth every penny. Update: it's been 4 years now and still love it just as much.

### ⭐⭐⭐⭐ Decent mattress.
*by S***4 on March 21, 2020*

I would say the jury is still out. I do believe I'm sleeping better and the comfort level is good. It is softer than other mattresses we have for exame Tuft & Needle original which I like. I think I have less pain in the morning. The biggest issue we have is that while sleeping you do sink into the mattress and the the foam fills back in during the day. Which is really just different, not saying it's bad. I would say it's the closest thing we've slept on that is similar to a water bed. Now, we liked our water bed, but we were a lot younger then. It is a 72" wide mattress. Our fifth wheel originally have a 70" mattress. We put a topper under it to raise it above the side tables, which could have an effect on what what we're feeling. Hope this helps. Filled out nicely when we unpackaged it. The cover quality seems good.
