This mattress is perfect for this tent, all I have to do is open the vents when I close it and close them a minute after I opened the tent. I can even adjust the softness by closing the vents before the mattress is fully inflated. I have the extra thick mattress under it and a heating cover over it, no problem.
Followed the directions, overinflated, and left it for a few days. Super comfortable, haven't tried as our only rooftop mattress yet, but it is perfect over the 2" mattress that came with the tent!
Man, opened it up and it was of course thin before it took in the air to maximize the mattress but then I added air with a small handheld amazon rechargeable pump. Unreal and mad comfy!
This is very comfortable however, it feels more like 40 percent foam and 60 percent air at best. Not 80 percent foam and 20 percent air. All in all though, very happy with it and the shipping is very fast. Thank you.
Although I was told that this mattress was intended to replace the one that came with my Evolution Tent, I used it as a topper and was pleased as punch. Might use it as a replacement in the future, but for now, this old back is likin' it as a topper ... even though it's tough to deflate!
