Carefully studied design starts with the frame, the quality of the supports. Ergonomics dictate the seat position. Two complementary ways to approach comfort: support and envelop. Chairs and armchairs have an upholstered shell which rests on the base; while the chaise lounge and armchair have the covering directly fixed to the frame, a sac which supports and seduces the occupier. The name, taken from the Caribbean liqueur made from coffee and rum, is about double identity, an allusion to a game of opposites. Posture which is both formal and informal, the symmetry and asymmetry of the armrests, the angularity and curvaceousness of the frame.
