Tortello emerges as a standout monolithic armchair that impresses with its large, plush, and inviting contours. Its name straightforwardly signals its remarkable design, which incorporates a variety of unexpected features. The base of Tortello, a unique tray with a trapezoidal section, is crafted from recycled polyethylene using rotational molding. This is complemented by an elastomer mattress, upon which rests a foamed upper layer encased in soft fabric, notable for its distinctive shape achieved through special 'pinched' stitching. Tortello is a testament to responsible manufacturing, employing advanced technologies and materials. The focus on sustainability is evident, from the use of second-life polyethylene for the structure to the addition of polyurethane foam and thermoplastic elastomers that enhance its shape and comfort. Despite using minimal polyurethane, softness is assured through meticulously chosen construction techniques. The innovative choice of materials and the method of assembling structural elements without adhesives or glues mean that Tortello can be fully disassembled, simplifying recycling.
