Coffee shop chair no.14 by Michael Thonet has been in continuous production since 1865, making it one of the most successful mass produced products ever. It's made from six pieces of wood held together with screws and bolts, with a cane seat.
Thonet experimented with lamination to make curved wood, but finally settled on steaming the wood to curve it. A process called Bentwood.
(Does this remind anyone of Eames?)
