Sealed Chair was the result of the research and development of an accessible and affordable serial production process. The chair furniture comprised three extruded plastic rods made flexible by heating in an oven.
After having been formed in wooden templates, the parts were linked using a welding technique that pointed the melting of the plastic: a seal. Those seals were made from imbricating the templates together as a puzzle. Depending of puzzling two or tree templates, the outcome of this mould became a chair or an armchair. The construction of the chair was the result of drawing with these bending and welding techniques. Each part worked in synergy with the others. The ensemble was stabilized.Cologne 2011: the chair as part of [D3] Design Talents was presented by designer François Dumas of the Netherlands at imm cologne in Germany. It was called Sealed Chair. The chair design was made from heating plastic rods to make them flexible then setting in wooden moulds – much like the production of bent wood furniture. Whilst the rods cool, the connection points were fused and the moulds joined together. The melted areas against one another were pressed to form a seal and the joints of the chairs. Three rods were needed to make an armchair while only two were taken to make a chair. A more durable version of the seat was also created using a stronger thermoplastic and screws. Imm cologne was placed 18-23 January.
