If I weren’t American maybe I’d have better examples (the knights’ round table!) but for me a lot of famous furniture is presidential: the desk in the Oval Office, JFK’s rocking chair, and FDR’s wheelchair. When I mentioned this recently it led to a discussion on whether a wheelchair is proper ‘furniture.’ A friend with a loved one in a wheelchair argued it was an instrument of mobility and absolutely not furniture. While primarily a mobilizer, as soon as a wheelchair pulls up to a desk or a table it also serves as furniture. Anyone can park one in the living room, whether they need it to get around or not. Same with a dentist's chair. No disrespect intended.
Many things not designed to be furniture end up as furniture. Take those cable spools that get made into coffee tables. Or milk crates used as modular shelving. A sail can become an indoor hammock. Today I saw a horse carriage seat repurposed as a bench.
Anyway, back to the presidents. Surely the best piece of “presidential furniture” is Thomas Jefferson’s revolving book stand. I thought of it this President’s Day when I was sitting at my desk, my eyes traveling from a newspaper, to a book to the computer screen. I think of the stand, which holds five books, as a precursor to internet tabs.
