Miami is one of the world's capitals for midcentury furniture, but out of all of our high-quality outlets, the largest and most diverse is Miami Art and Design Expo. Run by brothers Robert and Carl Massello, M.A.D.E. features booths sponsored by a variety of local dealers, all of whom have favorite styles, designers, and periods, so you'll find bureaus rescued from the old Eden Roc Hotel next to Sixties Brown Jordan outdoor furniture next to Eames Eiffel-base plastic chairs. Come prepared to haggle (prices are quoted on-site) and to spend more than you would at a thrift store. The dealers select the best pieces from estate sales, conventions, etc., so they know the value of everything, and you should too. It's also advisable to come often. The Massellos are nice guys who reward repeat customers, and some of the best stuff hits the showroom floor in the morning and is gone that afternoon. But be careful of developing a designer furniture obsession, or M.A.D.E. might become your second home.
