BRERA | Upholstered bench
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.
