Furniture Design Chicago Line Armchair by Alexandre Kasper Chicago Line is an armchair with a matching ottoman, designed for long periods of seated rest. The armchair is made of solid wood machined with five axis technology, and the arms are shaped on a computer numerical control lathe. The seat combines two gentle curves that follow human anatomy with high performance foam. All wooden parts are machined so that the armchair appears as a single piece. The form is inspired by the modern and industrial architecture of the city of Chicago. The ottoman extends the comfort and completes the set.
