Super comfly. I sleep on this mattress with my sleeping bag and a pilllow if i can find one and sleep great. I've only used this about 10 times and I don't have an electric pump so I would definately recomend getting something like that. I underfill the mattress a pretty good amount because I tend to sleep on my side and it's way more comfortable that way. I'd recomend getting this especially if you see it on sale. I got mine for $8 but it is currently $20.95.
