For this design, there were a number of sources that helped inspire its formal qualities; from the sinuous shapes of a human body, to the works of Hector Guimard, to rock formations carved by natural forces.
In addition, the inspiration for the interlocking connection joint came from studying religious book stands that are carved from a single piece of wood and feature two interlocking parts.
The swiveling action of the chair also helps reduce its original volume by half, making it easier for shipping.
UNIQUE PROPERTIES / PROJECT DESCRIPTION:
The Stratum chair was born out of a desire to create a piece of furniture that expresses its function and the material it uses in a very organic fashion, while taking advantage of advanced CNC milling and fabrication technologies.
Its unique formal and visual qualities are born out of the ways in which the plywood strata layers are carved to highlight the chair's functional features.
Its termination at the ground with three legs also accentuates the design's edginess and give it a sense of delicate balance.
OPERATION / FLOW / INTERACTION:
PROJECT DURATION AND LOCATION:
The project started in August 2013 in Ann Arbor, Michigan and finished in December 2013 in Ann Arbor, Michigan, and was exhibited in SIKKA Art Fair 2015 in Duba, UAE.
FITS BEST INTO CATEGORY:
Furniture, Decorative Items and Homeware Design
PRODUCTION / REALIZATION TECHNOLOGY:
The main parts of the design are composed of laminated sheets of Baltic Birch plywood. Most of the features of the chair, its sharp edges, flowing form of its back and seat, as well as the central interlocking joint were designed to leverage the extra axis of freedom that a 5-axis CNC milling machine offers. Multiple iterations of those features were produced made to properly calibrate their fabrication process while maintaining a strong design language.
SPECIFICATIONS / TECHNICAL PROPERTIES:
530 mm x 758 mm x 865 mm. After folding, the chair dimensions are reduced to 530 mm x 316 mm x 933 mm.

The most difficult part of the design was figuring out the interlocking connection detail. This involved multiple studies in terms of design, but also from fabrication point of view.
