what kind of mat would be good to sleep on every night (instead of a bed)?
I don’t know how to get around the sheets and blankets hassle, but I slept just fine for about a week or two on an egg crate mat on top of a folding gym/camping-type mat (the sort of material you’d use for tumbling). The egg crate mat rolled up and the folding mat folded in thirds from a narrow twin-size mattress into a square. I don’t know why that combination worked, but it did.
I slept on one of these for more than a year. Eventually it got a little thin in places, but they’re pretty well made. They fold far more easily than a twin futon mattress (not a bad idea, but I wouldn’t plan on easy storage) and they’re cute, too. Urban Outfitters has a few different designs and they also sell frames like the one in the picture, but I was totally happy snuggling up on the mat without any frame. Also because they’re so cute They work well for extra seating and you could use it without a sheet– just buy one of these sets and you’d have a very easy to store semi-permanent bed solution!
