E3 prototypes, constructed of Medex fiberboard, were cut using a CNC router.
The final product would be constructed from polyethylene which is a lightweight, durable material that is strong enough to support both children and adults. This feature also allows for reconfiguration by all ages. Polyethylene will produce a smooth surface with rounded edges and is 100% recyclable. Rotational cast components will have a fine, orange-skin surface that hides marring yet won't transfer a texture to writing or drawings when used as a work surface or desk. It is also easy to clean.
