Coleman ComfortSmart Cot 

I bought the 69' version of the Coleman ComfortSmart for the back of my Honda Element to use for camping. This would also work great for camping in a mini van. i have also used it in a tent. It's comfortable, and folds up easily. To store, remove the mattress, flip the cot over, and put the mattress on the "bottom" so it stores on the inside when folded up. If you are over 5'6 or 5"7 you will need the larger size. The mattress can slide around a bit so I put some non slip shelf liner between the cot and mattress.
