Mould a butt-shape into the short sides of a beer crate to enhance comfort when sitting on them.
Pop quiz: Where does one get the best ideas? Right, at parties! So did I. Another question: on what does a Dutchman sit when all seats are taken at a party or on the camping? Right, on the side of a beer crate! They are solid (because of the enforcement within the crate to separate the bottles), they are lightweight and they have nice colors.
So why did no one think of way to make these things comfortable? A crate with a pre-mold butt-shape on the short sides for example! This is only the `economy` solution. It would be also nice to have an integrated polyester cushion instead of the butt-shape. This would be the ‘deluxe’ version, also easy to clean.
As an extra addition it would be nice to integrate a small ashtray in the form of a small, partly removable, drawer in de sides of the crate. This could be even an extra idea for halfbakery.
