We will be camping multiple times with friends of ours this summer. Their camper has a hide-a-bed, which probably had the original mattress on it. I bought this mattress for them. We slept on it for the first time last weekend. I slept great. My husband said he could still feel the hide-a-bed springs through it, but I definitely couldn't. We both slept well. When it came out of the box it was very flat, but it fluffed up over the course of a few hours. They try to leave the bed folded out when they aren't using the camper, as that way the mattress can stay fluffy and not get creases. Also a plus is it comes with a zip-on cover, so it'll be easy to take that off and wash it. Full size sheets fit fine on it. I'm definitely glad we got the 5" and not a thinner memory foam mattress. I was worried the memory foam would be too soft, but it has decent support. Definitely not something I would want to sleep on every night, but like I said, works great in a hide-a-bed.
