The shell is made from MAGNUM 3404 which is extrusion/thermoforming resin.
3: Seating foam HR 50 High resilient foam in a fire retardant quality. Safety foam 10529. This type of foam is a development of the original polyether foam. Ad 4: Leather The chair can be upholstered with different types of leather. Our standard Camo leather is Nevada. Nevada is a full-grain, vacuum-tanned, smooth aniline leather. The hide is firm, but supple with an exceptional grain. The best choice when looking for Saddle-type leather. Visible insect bites, healed wounds and fat stripes contribute to the exclusive look. Colour variations in the hides must be expected. The leather can withstand dipping in water. Chrome tanned type III made without the use of PCP and CFC, which are harmful to the environment. Ad 5: Transport box Quality 291 BC 7 mm. The cardboard boxes are made with 2 layers of corrugated cardboard and 3 layers of cardboard liners. The layers are glued together with corn glue. Both cardboard and corn glue is 100% recyclable. Maintenance guide for the 5 components After being used for a week to 14 days the bolts might need to be tightened. A B The Bolts, see drawing above, must be tightened firmly with an umbraco key. There are 2 bolts on each side where the legs meet the frame (A) and 2 bolts on each side where the legs are connected with the distance piece (B). The bolts must hereafter be tightened if needed.
1: Chrome platted steel The chrome plated steel can be cleaned with a dry and clean cloth. It is only to be cleaned with a cleanser for a chrome platted surfaces. Do not use any polish cream or other chemicals on the chrome platted steel surface. 2: Polyester shell No maintenance required. The shell may change shape exposed to more than 80 degrees Celsius. Do not place the chair in front of a fireplace or other heating devices. 3: Seating foam No maintenance required. 4: Leather We recommend that you hoover your furniture regularly with a soft brush attachment. This will prevent dust particles from settling on the surface. In some cases thorough cleaning is essential; use a solution of distilled or boiled water with natural mild soap flakes of the highest quality (half a cup soapflakes to one litre of hot water). Whisk the soapflakes into the hot water and only use the foam. Apply the foam, after it has cooled down, to the upholstery with a soft cloth, without soaking the leather. When the upholstery is dry, wipe it down with a soft cotton cloth. In time the leather might need nourishment like leather grease. 5: Transport box No maintenance required. Even though the product is very environmentally friendly we recommend the product is returned to a licensed recycler.
