Polish designer Oskar Zieta has designed a metal stool called Plopp for Danish furniture brand Hay. Update: this project is included in Dezeen Book of Ideas, which is on sale now for £12.

The stools are made from hydro-formed metal; two sheets of metal are welded together following the outline of the stool, which is then filled with fluid under pressure.

The legs of the stool are then bent into place, creating a form that Zieta likens to inflatable furniture.

"The result is a light construction which can be easily mass-customized at low production costs with well established techniques," says Zieta.

The stool PLOPP designed Oskar Zieta for HAY

Idea: 
The idea was to produce a stable and convenient furniture out of thin metal sheets using the potential of hydro-formed metal surfaces.

This was achieved by placing welds along the outer contour line and the interior. The interior welds as well as the pressure of the poured in fluid applied limits and control to the formation of interior cushions, creating the final shape resembling the pattern on the BlowUp Furniture.

The result is a light construction which can be easily mass-customized at low production costs with well established techniques.

Novelties of the process:

  • industrial production with a unique result
  • every single furniture is a unique sculpture
  • combination of creative freedom with a consistent production process
  • creation of a handmade expression produced by CNC machines
  • unlike other CNC manufactured products with identical expression, PLOPP looks like a one-off handmade product
  • application of modern techniques and materials for a retro futuristic design
  • combination of stability with minor production effort and simplicity resulting in an appealing look.

Production process:
 PLOPP can be manufactured with different metals like steel, chromium-nickle steel and various alloys.

First the metal sheets are welded together at the contour of the final shape. The following application of a spot-welding raster is essential for later forming processes.

This grid is depending on the overall dimensions of the stool. The hydro-forming process applies liquids with high pressure to the water-tight welded inner space.

This pressure and the thickness of the metal sheets define the 3D appearance and stability of the stool. In the last step bends are applied to the inflated shape, thereby folding the stool into its final form.

    a celebration of manufacturing, clever use of technology and material, pleasing to the eye results… but how pleasing could it be to the person seating on it.????

    ….i hope it is L

      I agree with you completely: To me, good design is all about maximizing the benefits of a particular industrial manufacture method, and in doing so, achieve beauty within function. But i think these babies needs pillows yes?

  • kingmu

    cunning… and spectacular.

  • Alejandro

    koons?

  • Boeing777

    quite a nice pick for the colors but will people’s butts find them appealing…?
    mine thinks it’ll hurt.

    Very nice project…
    I remember seeing a video a while back while they were being inflated.
    Any links for that?

    nice, reminds me of the Chapmans brothers sculptures Death I and II (2003/4), cast bronze inflatable sex dolls. both have this great ambiguousness of material. not sure if the stool would be very comfy though.

  • lars

    i would be honest and just call it sculpture (and post it
    on a different blog subsequently).
    can’t imagine to really sit on it. must hurt…
    also, there are stools more comfortable, stackable
    and more affordable on the market. so what’s the
    point?

    looks very interesting but i don’t know if it’s comfortable. and if it needs a cushion this will really blow away it’s visual effect

  • jwal

    I saw these in a shop in Copenhagen and they are really stunning.

  • yung

    I’ve tried it… not really comfortable. But still a cool piece of furniture.

    I saw them at an exposition at the ETH last month, apparently they were (partially) developed and produced by some of the architecture students. They look nice, but I can’t imagine sitting on them for a long time..

  • joe

    looks a lot like chris kabels seam chair to mee..

  • Aurelius

    i saw them at designers saturday. it’s comfortable enough for a chair like this. and it looks great!

    Bizarre.. inflatable metal stools! Odd but I like the concept and they look pretty cool too. Although they don’t look all that comfortable to me.. But that’s something you can’t really tell from a photo.

    Are they ‘inflated with the fluid & then the fluid removed? And if so, does that effect the stability? Very interesting stuff, think I’ll be musing on this for a while today!

  • Geoff

    Could one Plopp one through the hole in the seat?

  • Tammy

    Where did the fluid go?

    I like the process of doing this objekts, simple idea for a piece of art.

    i thought the whole point of it was so you could crap in the whole…. i mean plopp stool?? Really!

  • KM Design

    Really interesting. I have seen a friend try to inflate metal and noticed it was quite difficult and quite dangerous if you don’t weld it properly.
