The Istanbul Arm Chair is a contemporary, minimalist chair suitable for both residential and commercial spaces. The internal frame is made from solid birch wood. It is upholstered in black PPM (100% polyurethane) upholstery and the base is tubular polished stainless steel. PPM (Polyurethane-Polyester Microfiber) is a new upholstery material that has many advanced features including breathability, super durability, easy cleaning and maintenance. It is suitable for all climates and with its high durability, it emulates the finest leathers. PPM’s 1.5 mm thickness gives reliable strength that also resists tearing, sagging, crocking and shrinking. PPM is recommended for high traffic commercial environments. Occasional dust cleaning with a clean white cloth is recommended. If needed, apply soapy water, followed by wiping down with clear water and drying. This modern chair is also available in grey fabric.
