This is the Camp Daybed from designer Stephanie Hornig. It's a daybed with an integrated sleeping bag. Sure you could just lay a sleeping bag out on your existing couch, but if you don't bungee-cord yourself to the frame.
I maybe like this idea with the wooden beam at the end of my bar. maybe the wine in on the side of the bar opening only. :) Diy Wine holder, (maybe bigger beam in natural looking wood where you cant see the bottle neck)
