Borge Mogensen was already referencing historical classics when he designed J52B, his take on the English Windsor chair, in 1952. The Windsor chair was a solid and comfortable chair with roots in 16th-century England, and here FDB Mobler's head designer tried to lighten the expression with a range of simple staves. The result was a very comfortable chair with a simple and functional expression. The chair was reportedly President Kennedy's favorite chair to relax in. It can be used both as a dining chair and as a lounge chair.
