Contract seating design and manufacturing company Morgan Studio’s RIO line of seating, incorporate several different variations that share the same basic structure of the chair. RIO chairs offer several different backrest options, including an upholstered back, a natural timber option and a 3D printed option available in multiple finishes. The lattice framework on the back of the 3D printed chair is generated using a mathematical algorithm that removed as much material as possible and also made small adjustments to the lattice pattern, so each set of 6 3D printed chairs is slightly different than the others.
