Unique Properties
Ydin stool can be mounted without using special tools, thanks to a simple interlocking system. The 4 identical feet are placed in no particular order and the concrete seat, acting as the keystone, keeps everything in place. Easily machined feet are made with scrap wood coming from a stairs manufacturer and finally oiled. The seat is moulded in a lasting fiber-reinforced concrete. Only 5 dissociable parts to be flat packed and ready to be shipped, is another sustainability argument.

Production Technology
For a good fitting assembly, the hole dimensions in the center of the seat had to be extremely precise. So the mould has been made by using a 3D printed model. Then, the concrete seat remains raw from mold release. Feet are made with traditional woodworking technique by using several jigs or machining setups. With only 1 kind of piece to be shaped, it gives a very good process optimization when you start to manufacture several units. Scrap wood is the only raw material used for making them.
Design Challenge
The biggest challenge has been the technical and formal assembly development. The positioning of the 4 wooden feet one to each other, first. And secondly, the base interlocking into the seat. While having to meet the production capacities of a craft workshop.
Research
Project started with the desire to work with Ultra High Performance Concrete (UHPC), without knowing what kind of product was going to be obtained in the end. Soon, the choice to combine concrete with wood seemed to be the way not to get a single monobloc object that could just have been in molded plastic. Technical characteristics offered by this concrete, have allowed to develop an assembly principle that would not be possible to achieve with other materials, in a craftsmanship context.
Inspiration
The idea of a stool comes by experimenting with Ultra High Performance Concrete (UHPC) moulding possibilities. The final drawing of the furniture has been inspired by Scandinavian design culture.
Project Duration
The stool development was spread over two years, but not as a full-time job. This is an internal project that came to life between the requests performed ​​to several customers.
Operation Flow
With the fitting mounting system of the Ydin stool, the disadvantages of a furniture kit are deleted. No hardware need that requires the use of tools. Feet nesting is carried in an instinctive way without the need for a manual. The assembly principle is idealized in the middle of the seat and participates in the overall aesthetics of the piece of furniture.
