kyouei design: construction chair

‘construction chair’ by kyouei design

kouichi okamoto of kyouei design continues his artistic research of metal chairs with the ‘construction chair’. the first in the series was ‘composition chair’, which was handmade by okamoto and developed by bending 3.0mm hard aluminium wire and crossing it one by one without the use of fasteners or welding.

this follow-up seating object is made of 481 0.5mm thick square copper pillars that are stacked precisely upon one another and soldered together into the final form. the chair measures 700 x 640 x 700mm and has a total weight of 120 kg.

with ‘composition chair’, kouichi continues his exploration in how materials evolve and age over time. when these images were captured, the chair was only a week old but already started to show signs of patina, accenting the lustre copper surface of the seat with hints of green.

the only tools used for this design were a jig and a pair of pliers. the chair which measures 700mm x 640mm x 700mm, weighs 60 kg and took more than 6 months to produce.

  • Kris, did you actually read any of the other comments?

    point missed
  • If you look back in history, you’ll find out that people have always worked with metal to create chairs that for different reasons were heavy.

  • initial reaction to this chair (I cant exactly put my finger on exactly why and of course I could be wrong) tells me that kouichi didnt go to design school. Then I thought, what a snob I am, this chair exactly represents a cornerstone of the designboom philosophy (of which Im a fully paid up member) and something that should be embraced. Now I feel confused, and I think I like it

    nice chair
  • insane maybe, but beautiful

    bren
  • weight (120 kg) x cost of copper per kg today (9.50USD)
    = 1140USD of copper… yikes

    also, the making of the ‘composition chair’ looks insane!

  • Pretty. Also, makes me think of Minecraft.
