Quoted By:
lately I've been sleeping on the couch and I've found that the fetal position is a very comfortable position to sleep in as long as you have something like the back or arm of the couch to brace against. its also has a small footprint and is about as thermally efficient as you can get. so I was thinking. what if i got a latge inflatable dog bed and slept in that. for the same weight and volume you could have like 4 times the padding and insulation.
