holon institute of technology graduate chen zalkind has created his own studio, ‘ZALKIND’, specializing in furniture and consumer products made using a wide range of materials and technologies. having grown up on a kibbutz, zalkind was surrounded by many industrial factories and small workshops teaching him about the various uses of materials.

in his latest collection, ‘internal pressure’, zalkind developed a special joint that consists of two wooden dowels that were locked into a pipe using pressure, without the need for glue or screws. ‘the pipe was switched out for a wooden plank and the joints continued to evolve.‘ explains the designer. ‘this stage was full of experimentation with the materials and the many different ways I could use the joint that I was developing.’

after the project had a plethora of material to work with from all the experimenting, the next step was the implementation. for this step, zalkind matched each joint to a different piece of furniture. out of dozens, three pieces of furniture were chosen; a chair, a bench and a coat rack. the next stage was to work on the actual design of each of the pieces of furniture. the chair is based on joints where the leg and arm rest meet and are locked into place by the seat of the chair.

due to the strength of the connection there is no need for stretchers between the legs. moreover, every time you sit on the chair it tightens the pressure on the joint and therefore ensures the durability and long life of the chair. the connecting angle between the leg and the arm rest can be adjusted in a way that allows three main advantages: a wide and stable space between the chair’s legs, appropriate space between the armrests and a comfortable backrest angle for the person being seated.

the parts for the bench, chair and coat rack are each created and finished independently, which allows them to be sent in parts to the distribution centers in an effective manner. moreover, the unique pressure connection diminishes the need to use glue or screws — the pieces are made entirely out of one material: wood. this makes the assembly faster, cheaper and eco-friendly.

the bench is based on a joint that is made up of two legs, a separation element made from oak, and a locking surface which is used for the bench seat

the ornamental brass ring clasps the rods to the wooden ‘seed’, thus binding all the pieces together into a product

the bench seat is made from veneer panels of oak and gaboon, they are placed in a crisscross pattern and laminated together

  • How is the backrest attached to the uprights? It’s not clear what is keeping it in place, especially if the chair is knocked over, or someone leans more heavily on one side or the other.

  • Wow! Reminds me of the genius behind the Westport chair and its connecting method. Well done.
