I would be very interested in testing out the Linon Chair and Stool by Alberto Vitelio. The pair might come across as being a little on the stiffer side of the comfort scale, but each one seems to have been constructed in such a way that caters to ergonomics. The armchair, for instance, features a nice reclined backrest with a generously angled slope designed for maximum relaxation.
The creator was playing with structure and geometry while composing these two pieces, choosing slender metal bars for a rigid frame and planar panels of plywood to construct the seats. The resultant forms of the Linon Chair and Stool suggest more space than they actually occupy, ultimately paying homage to modern furniture design with a fresh take to intrigue the contemporary taste.
