Awesome RV mattress!!
What a great mattress!! Of course, anything would be better than what came with the new RV, but this mattress exceeds all expectations! It very quickly inflated to about full thickness in an hour and by the next day when I checked it, it was perfect. No odd odor, great support in any position, and fits perfectly on the frame. It’s both firm and soft at the same time, if that makes any sense. No sinking - just cloud like comfort! We can hardly wait for our next camping trip! Well worth the money!!

Memory foam mattress? This is THE ONE!
My husband and I both have bad backs. Our problems are not the same and we both like this mattress. I'm not going to exaggerate and say it's like sleeping on a cloud or all of our problems while sleeping are gone! They aren't gone for me. My arms still hurt and then my fingers get numb and tingly or my hips will still ache causing pain all the way to my knees and sometimes ankles. I will say that I don't have to drag myself out of bed anymore. My lower back is not crippling me after being in bed all night. The bed is just firm enough to keep you from sinking into it. For me the mattresses you sink into are awesome when you first get in, but then I can barely turn over and my lower back feels like it is swayed when I'm on my stomach. OUCH! This mattress isn't too firm though. I don't feel like I'm sleeping on a covered rock. I noticed in some reviews people thought the mattress had a smell at first. My husband unpacked the mattress as soon as we got it. I was thinking, "My queen size mattress is in THAT box?" I knew how they were shipped, but seeing it in that box was crazy! He got it out and opened it up, so it could puff back up, and left it for a few hours before looking at it again. It didn't take much time for it to reach it's full thickness. We slept on it that night with no smell of any kind whatsoever. We both are satisfied with our purchase. We never expected it to take away all of our back problems. It's a mattress, not a miracle. Our expectations were met and we sleep as comfortable as possible considering. My advice to you is not to think any memory foam mattress will solve all of your sleep issues. I am totally happy that it made my night, and then my morning, more comfortable than I've been in years. I still have some problems, but they have been lessened by sleeping on a great memory foam mattress. Would I suggest this brand of memory foam mattress to family and friends? Absolutely. The price is comparable, or better, than other brands and it came within a few days of ordering. It's been a month now and we have no complaints. If you are looking for a great memory foam mattress, and don't want to use all of your savings to purchase it, then this is THE ONE! Good service, good quality, good price, good night's sleep. What more could you ask for?

Incredible Value! Comfortable Sleep. Only regret not buying this sooner.
Yeah, ok, here is another 5 star review. I will come back if I find something to knock back a star. First off, I did a LOT of homework before ordering this mattress. I read tons of reviews and as many independent reviews as I could find. A couple of conclusions lead me in this direction. 1. Trying out a bed in a store as apposed to buying on line did not lead to a higher satisfaction rate. 2. Spending a lot of money on a mattress also did not appear to increase satisfaction. So my starting point... I have a lovely antique butterprint bed that is 3/4 sized that I wanted to keep. I had been sleeping on a (very old) mattress on top of a (very older) box spring with a one inch memory foam topper. I was reasonably comfortable curled up in my divit that had formed; I like a soft bed and this fit that bill along with significant amount of hammocking; then came the boyfriend. While he never complained about the bed, when I mentioned I had intended to replace it for years the truth that my mattress bothered his back and the amount of hammocking was extreme for him was a tipping point. Then came the flurry of activity. Research and shopping for me and removing the old box spring and creating a platform bed out of my antique bed for him. He likes a very firm bed and I a soft bed. (My hips don't like pressure points!) I decided to shoot for a mattress firmer than what I thought would be comfortable for me and add toppers as needed. I could always make it softer, but never make it firmer. My research led me to several beds in the $600 to $800 range that sounded like good bets. But then there is the 3/4 size antique bed that is only 75 inches long. Zinus sells a short queen! I bit the bullet and hit the order button. We are both very comfortable! I did keep my one inch topper that seems to work for both of us. In fact we find it as comfortable as the $2000 mattress at his house! It is a lovely balance between enough "mush" for my hips and firmness for his back. In fact I am liking the firmness under the "mush" more than I would have thought. I have gotten better quality sleep than I have for years and hey, sleep is a great thing! So far, the mattress is a keeper and so is the boyfriend!

Firm and comfortable mattress.
The mattress fit our RV short queen area just fine. It might be a hair wider and longer than the original mattress that was in the camper when purchased new but it still fit. Very firm and quite comfortable. I am happy with this purchase.

Would buy it again.
Great mattress, firm yet contours your body. Very comfortable. No more sore knees or hips. Love it. Fits our class C motorhome perfectly.

Was skeptical but after reading the all reviews good/bad I waited for the price to drop and purchased the unit. Mattress arrived early, nice, and was well packaged. Opened the unit and placed it in the trailer it fit perfectly. Could see it start to expand immediately. No odors at all which was a very pleasant surprise. After 24 hours was 8 inch and one corner was only 6 inches. Punched the corner a bunch of times and sat on it to compress it a couple of times. After 48 hours was fully expanded to 10 inches all the way around, could not tell which corner had the issue, bonus! Never slept on a foam bed so expected to take a couple of nights to get used to it. Sitting on the edge to take socks off mattress really compressed and I though oh no what have I done, bounced right back once I stood up. After sleeping on it for 4 weeks, took it into the house to test, here are my thoughts. Like any memory foam product it does form to the body within a couple of minutes of lying down so if you do roll over you do notice that you are in a slight depression not an issue for me or my wife. I cannot feel my wife moving on the bed if asleep very nice. Find that I get neither hot or cold on the bed. Yes they say the bed is firm and it is but I would not call it hard. No issues sleeping on it and no pressure points throughout the night, sweet. Final thoughts rated it fairly it was exactly as stated and exceeded my expectations particularly for the price. Fits perfectly for what it was purchased for, Expanded fully, I find it very comfortable, almost like better than my own bed, price was excellent. For sure it is a 100% improvement on the old 5 inch coil trailer mattress, which it going to be recycled. A winner all the way around in my mind

Bought this for our camper and it was great. Not only was it comfy but also didn’t get super hot in the summer. It’s memory foam so it was nice with the kids crawling in and out all the time. Would definitely buy again!

We actually purchased one of these for our bedroom initially and after discovering just how comfortable it was, we decided to replace the absolute garbage mattress in our trailer with one of these as well. For a mattress they are very lightweight, and contrary to other reviews that I have read you do not have to cut the plastic and jump back out of the way because it flies open. It actually opened very gently. People probably spend a third of their life in bed, so if you want comfort I would absolutely recommend this product. The washable cover is an added bonus. The only drawback was the one we got for the trailer did not have a cutting blade with it, the one we got for the bedroom however did but the blade was inside the packaging so you had to cut the plastic open to get to the blade. Oh well, it makes for a nice new milk bag opener anyway lol.

Our first purchase of this mattress was of poor quality, as it never fully inflated. Part or the mattress was 4 inches thick, part was 9.5 inches thick. We returned that mattress and ordered again, this time it fully inflated, is comfortable and the return was easy to do. I would recommend opening the box in a warm environment, as we opened it initially in our cold trailer. The 2nd mattress was opened outside in the sun on a warm day, it fully inflated and has been a great mattress for us.
