francois dumas: sealed chair + armchair

‘sealed’ chair and armchair



‘sealed’ chair and armchair created by french designer françois dumas consists of three plastic rods made flexible by heating them in an oven. after having been formed in wooden templates, the chair parts are connected using a welding technique that melts the plastic to create a seal. those seals are made by imbricating the templates together much like a puzzle. depending on the imbrication process of two or three templates, the outcome of this mould is either a chair or an armchair.

the final construction of the chair results from the bending and welding techniques applied. each part is intended to work in synergy with the others, thus, stabilizing the ensemble.

  • Pourquoi utiliser des masques à gaz pour tordre des bouts de plastiques ?

    fukuda says:
  • hahaha, surtout qu’il n’y en a qu’un qui tord !

    meta says:
  • congratulations, great work says:
  • Le Thonet nouveau est arrivé!

    Augustin says:
  • I think….the very hard work has paid off in the elegant, functional and eye-calming result. I rate it A+ and hope to buy a set from you in the future. Though I prefer easy-to-replace non-chemical materials, this is still an example of how plastic can be put to good use.

    charles says:
  • ah … the French, always start by criticizing …
    what pity

    considering the work done by François begins by saying “Bravo”
    when designers are making things in volume and not only in 3D (!) …
    it starts to become more interesting when we talk about design
    but for that you need a top talent ..

    I say again, congratulations and I look forward to seeing more projects
