[ch]air has been assembled from laser-cut ‘zigzag’ strips of cast acrylic, which have been slotted together to from a lightweight framework. The geometry has been informed by the self-organising principles that govern soap bubble cluster formation (the observable rules which ensure that cumulatively each bubble encloses the maximum volume of space with the least possible surface area of partitions).

A single bubble encloses the maximum volume of space with the least surface area of soap bubble film, forming a near perfect sphere. As bubbles merge together to form clusters they reorganize their geometries immediately, sharing partitions to ensure maximum efficiency in terms of the ratio between bubble cell volume and total surface area. In these clusters all bubble cell edges meet at a vertex, four at a time, at 109.5 degree angles.

Here the resulting lightweight framework is intended to resist compression with the least structural material, as an isotropic geometry. Each strut in the structure follows a geometry of shortest paths and, as all struts meet consistently at an angle of 109.5 degrees, loads are distributed evenly. Effectively the framework fills a predefined volume of space with the shortest possible length of a predefined number of struts, making them individually inherently resistant to buckling under axial compression.

This structure is not an exact replica of soap bubble geometry, but rather the 109.5 degree rule has been extracted and applied as an isotropic load bearing mechanism. However just as a cluster of soap bubbles will contain divided pockets of air with the least amount of material, [ch]air supports the sitter with a geometry that contains a maximum amount of interconnected empty space (in relation to other isotropic geometries). While this sounds indicative of an ineffective support system, it is actually a direct result of each structural element minimising its effective length, enhancing the efficiency of the entire framework.
