Charles Hess patented this combination piano, couch, and bureau in 1866, intending it for hotels and boarding schools in which some bedrooms are used as parlors during daylight hours. Closet F holds the bedclothes, and closet G holds a washbowl, pitcher, and towels.
Supposedly, the piano played just fine with all this furniture packed into it. I don't know if they ever actually built or sold any of these. Link -via Nag on the Lake
