Wow! This is not the most comfortable place to sleep because of the height and the open surroundings. Not to mention the dangers of possibly rolling over the mattress and falling flat on the ground. But can you imagine what the breeze is like up here?
Hold on! Before you say anything, this image is obviously photoshopped. There are lots logistical problems with lugging a mattress all the way to this peak, and then tying it so that it balances next to the cliff.
