You can sit on a washing machine, but that doesn't make it a chair. A transformation like the one industrial designer Antonina pulled off does make it a chair, though. And there are even DIY instructions so you can try too, if you're into that sort of thing.
As part of a project with the incredibly appropriate title "I used to be a washing machine," Antonina carefully dissected and old washer to make not one, not two, but three different flavours of chair, each a wonderfully stark piece of furniture in its finished form.
While all washers are going to have different innards, it stands to reason most of them would be kinda-sorta similar enough to pull something like this off. It also stands to reason that none of us will really bother trying. You can hop over to Designboom to look at the plans and see what it would be like if you did, though. (It'd be awesome.)
