STRUCTURES: Wood and wood derivatives used for the structures of all Busnelli sofas are FSC and CARB 2 certified, to ensure sustainable forest management and the reduction of formaldehyde emissions. The steel frames are painted with environmentally friendly powders, without volatile chemical compounds (VOC) and without harmful metals.

SPRING SYSTEMS: The spring systems applied use elastic criss-crossed belts (L 70 mm) with a high natural rubber content, characterised by a total covering of rubber threads. The high rubbery content inside the belt increases its durability and ability to rebound, thus returning to its original position even after years of use. The belts are pre-tensioned using a dynamometer to ensure uniform tensioning.

PADDING: All Busnelli sofa padding uses flexible polyurethane treated to 15-20% with polyols of vegetable origin such as soybean oil, which reduces greenhouse gas emissions by 36%, compared to traditional polyols derived from the chemical synthesis of petroleum. Also used in the padding are expanded foam, flexible foam in differentiated densities, shaped foam, regenerated PET and bonded resin fabric.

MOULDED FOAMED ELEMENTS: All elements produced using the moulded foaming technique are always provided with a disassemblable insert, whether in coniferous plywood or metal. This allows for greater recyclability of the sofa at the end of its life.

UPHOLSTERY: A collection of 30 types of upholstery in 419 colour nuances, selected from: high quality virgin fabrics, recycled, recyclable and biodegradable fabrics, leather and eco-leather. In particular, the Andante, Vivace, Adagio and Rec fabrics are derived from fully traceable recycled polyester and PET bottle yarn, generated without the use of chemicals. The production process is 100% made in Italy within a 90 km radius of the company’s headquarters. The use of recycled polyester requires fewer processing steps than traditional fabrics, resulting in reduced energy consumption and carbon emissions during the production process.

INTERIOR LININGS: All service fabrics feature exclusive Busnelli patterns, printed or woven directly onto the weft of the fabric (jaquard).

REMOVABLE COVERS: All Busnelli sofas have removable covers, whether covered in fabric or leather/eco-leather. The removability favours both the possibility of refurbishing the product according to new user requirements and disassembly at the end of its life cycle.

PAINTING METALLIC PARTS: The powder coatings applied are solvent-free and do not contain volatile organic compounds (VOC) or toxic heavy metals such as lead or chromium. High environmental sustainability is also given by the use of regenerated substances in the mixture. The powder-coating process ensures greater durability.

ACCESSORIES: The accessories of Busnelli sofas (trays, coffee tables, platforms) are made of coniferous plywood or MDF veneered in ash with an open-pore black varnish or lacquered (RAL) with a 10 Gloss water-based varnish cycle.

ADDITIONAL CUSHIONS: in Busnelli cushions, the upholstery is made entirely of regenerated PET resin. The application of different covers on the two sides of the cushions makes them double-sided and versatile, thus increasing the perceived durability of the sofa itself. They also feature the exclusive perimeter band with Busnelli monogram embroidered in shiny black thread on black canvas.
