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!
Nah, cause then I'd become a millionaire from selling my invention, have elaborate dance parties in my mansion, then get sued for not testing out my product on prisoners first and end up losing the case to a jury and judge that were somehow negatively affected by my shoddy product.
