Why doesn't someone manufacture this and make a bunch of scratch? You can also place a piece of ply wood on top of a stump and have a perfectly good table, doesn't stop us from buying tables.
It could fold up, have an auxiliary power line, a built in pillow, be scented. -You could change the scent based on the genre of film. etc.
Build it s_s, I'll come up for a logo for you :)
See ya soon pal!
