The RUTT chair is made almost entirely of polypropylene, except for the chrome-plated metal base and the metal frame of the seat that incorporates all the adjustment mechanisms and of course the shock absorber that can support up to 120 kg weight. Polypropylene is particularly resistant to weight and water, while it has great resistance to temperatures up to 125 degrees Celsius. Also, its durability is not limited to weight, water, and temperature, but it is unusually resistant to many chemical solvents, acids, and bases.
The upholstery of the chair is made entirely of high-quality PU leather. This is also known as synthetic leather or faux leather. It has a linen fabric texture. Synthetic leather is the evolution of leatherette but with the main characteristic that it is not easily distinguishable from real leather. Its composition is mainly polyurethane and micro-nylon fibers, unlike leatherette which mainly contains PVC.
