Modular Storage Seating- concept I'm working on, all parts are modular and interchangeable, and designed to add storage to a piece that usually ignores it, the sofa. Ends can be bookcases, or pull out drawers for storage or files, base can be sliding door cabinet, drawers, fold out bed. No back makes it a day bed. It's sort of based on the premise that "working at home" often means "working on the couch," and the problem with that is there's nowhere to put all your crap. Thoughts?
