Before the summer I bought an inflating full size air mattress for camping. It just fit inside my tent with no extra room. I bought it mostly to make my wife comfortable coming camping for the first few times. I knew I would need something smaller eventually. I got this great air pad on Amazon. $50 each. Two of them are way smaller then the full size mattress, and I don't need to rely on a motorized pump. Key criteria for our Denver trip. Click on for photos.
