STP in the USA

Back in the USA, the STP stool will soon be manufactured locally. Fabrication begins in the first week of October 2015. For information on availability and costing, please visit our website.

The final TPC protoype

With only four fastenings around it's perimeter the seat yields elegantly to the weight of the occupant.

STP at the DMY

The little brother of the PCH chair also made it's debut in Berlin. The tension straps prove really successful in distributing load across the stool making in very robust, despite using no glue or mechanical fastenings.

PCH Final Design

The PCH chair made its debut at the DMY. The final design employs Linoleum on Multiplex plywood.You can learn more at our website.

DMY Weekend

The DMY show proved to be a great way to gauge feedback on the new Erfindsam products and we hope to participate again in the future.

The DMY Show 2015

PCH prototype

The base construction supports the seat and back units; these are plugged together and bend to support the unique posture of the occupant. You can try the final version at the the Berlin design show.

PCH joinery detail

The PCH chair employs the CNC router to create a series of interlocking parts. With no adhesive or mechanical fastenings the chair easy to pack up and take with you.

PCH chair connections

The PCH chair frame comprises of a kit of parts that can be connected with a series of flexible fastenings. The frame is held in tension allowing for an elegant sloping form.

CNC Undercarriage

The seat and back support assume their form by being held under tension. The fastenings to the chair base are created on the CNC router and connect at the flattest point.

Core Support

Two interlocking plywood profiles are held under tension. The forms yield to the weight of the occupant but spring back to their original form when unoccupied.

Full Scale Prototyping

Unlike conventionally upholstered furniture the exterior material requires minimal internal support to maintain it's appearance. However in order to support the weight of the occupant; a simple armature must be provided.

The TPC template

The template is created in a very manual way reminiscent of tailoring.

The TPC Concept

The TPC chair seeks to repurpose commercial carpeting. The design takes advantage of it's capacity to be folded into a load bearing form.

TPC Fastening

Laser cut corrugated cardboard proves to be an effective way to explore the flexible junctions to the design of more complex furniture forms.

Flexible Junctions


The simplification of assembly has taken us back to our flexible 'inner-tube' junctions. They provide a way to to build non-perpendicular shapes.

LED Lighting Unit


The STG lampe is illuminated by two banks of high powered LED's. These are mounted onto miniature circuit boards and connected to the Arduino microprocessor. The colors and intensities of each end of the lamp can be controlled independently

STG Lampe

The lighting element is squeezed between the timber dowels and secured with a composite fastening.

Friction Fastening

The STG lamp employs 3D printed junctions. They use friction to secure each element and maintain equal spacing between each dowel.

Strength through Compression

In order to simplify the process of assembly we are trying to eliminate adhesive or mechanical fastenings. These sketch models represent junctions that simply brace materials together.

Repurposing Home Electronics

This hand held gaming controller is a product destined for obsolescence. Is there a heaven for unused devices?

As part of his course on Materiality in the Digital Realm, artist Wolfgang Spahn showed me how to steer the laptop by altering the device. In this example the “numchuk” is operating a small motor while data is simultaneously represented on the computers screen. In other words the devices are communicating with each other.

Rotating Light

This lighting unit is also a combination of optical illusion and physical computing. The unit has been fabricated from surplus Plexiglas and laser cut to form a kit of parts. A rotating wheel at the center forms one of three layers of perforated material. The core is illuminated by LED strips, each programed differently, to provide a variety of hues, intensities and unexpected variations in the outward appearance.

Tactile Surfaces


This video demonstrates the optical effects provided by the double skin of the tube light. When the object is touched, the effect alters in relation to the movement of the hand.

Licht Patrone

The strange optical effects created in the previous experiment, prompted me to produce a second, larger, lighting unit.  This version comprises of two layers of perforated material. The unit is hollow, allowing the light to be seen within and upon the surface simultaneously. This results in an enhanced three-dimensional appearance.

Red, Green and Blue


Returning to the Arduino, I explored how it can be used to control LED lighting. Programming allows the RGB channels to be controlled separately creating very subtle changes in the temperature of white. This means that the LED can offer both warm and cool light and offer variations of intensity preferable to the end user.

Flexible Junctions

A supply of cycle inner tubes enabled us to explore the many ways in which this flexible material can be re-purposed. These fastenings are strong enough to hold rigid components in place. They also enable the object to be deformed or assume a variety of alternative shapes.



Examining one material in great detail prompted us to think about utility but we also became aware of the unique appearance of rubber. These free play exercises produced some very elegant artifacts.
