Диван i 4 Mariani BRERA

The load-bearing frame is made of three different materials: the back is 20 mm thick poplar plywood, the seat is elm heartwood, and the arms are laser-contoured sheet steel.‎ The heartwood is naturally seasoned for at least three years in stacks on the company’s premises, while the metal parts are seam welded.‎ Dap joints unite the various wooden parts of the frame with securing cylindrical dowels.‎ The seat webbing consists of elastic polypropylene and natural latex belts in two sizes and different elasticity.‎ Belts 9 cm wide with 20% elasticity are fixed parallel to each other and perpendicularly to the length of Brera; these are alternately crossed by 5 cm wide belts with 80% elasticity.‎ The framework is fully upholstered in leather and a layer of polyester wadding is fixed to the back to provide softness.‎ The cushions are padded with sheets of resilient CFC-free polyurethane foam with variable density (between 30 and 35 kg/m³), covered with bonded plush and polyester wadding.‎ The back cushions are in Tecnolat, a mixture of 100% silicon-coated hollow staple polyester and natural latex foam cut into small lozenge-shaped pieces.‎ This innovative material provides the same softness as feathers, with the additional advantage of a “memory” effect—after pressure has been exerted on the cushion it automatically returns to its initial shape without having to plump it up manually.‎
