In an Igloo (multiple times)- Pretty freaking cold but you get used to it, the floor is hard as ice even with a pad, and when I did it there were about four othre guys which made it pretty awkward.
On a park table- Not bad actually, fiber-glass is best though
On a coffee table- I just did this as a joke for everyone who got a couch or bed
In the auxiliary parking lot at a fair grounds- It was for the centenial scouting Jamboree. I slept under the stars and in my boxers, so when I got up in the morning I decided to walk around abit with just a shirt, boxers, and boots. I got a lot of weird stares.
In a tent on the snow- pretty warm if you know what your doing
On the floor- it really comes down to the carpet, the tempature of the room, and how tired you are
On a friend's couch- smelt like beer
In a hut some friends and I made out of tarps, poles, and rope- pretty nice.
My own bed- I prefer one flat pillow, nothing special
