When Mr. Murphy patented his so-called "Murphy bed" in 1916, he intended it to be used as a space-saving measure by people of limited means and limited floorspace. Like a trundle bed (and, for that matter, tuberculosis and polio), the Murphy bed was an emblem of the early twentieth century.
Times change, however. Now that you've made it safely into the early twenty-first century, you can relive your nostalgia for that era by purchasing the Pet Murphy Bed by Midnight Pass. With the Pet Murphy Bed, your dog or cat (or ocelot or pot-bellied pig) can re-invent him- or herself as an immigrant, recently arrived from Ellis Island and now living in a small apartment on, say, the Lower East Side of Manhattan ... all for a mere $199.95 (plus shipping and handling).
