The Ozwald Boateng x Poltrona Frau Chester seating line features special upholstery in the Tribal pattern, conceived by the designer as a celebration of African culture and textile tradition. The pattern is applied using the hot embossing technique on Pelle Frau® Nubuck leather. This special technique, performed manually, represents a revolutionary innovation in leather processing. The backrest and armrests feature a handmade capitonné design.
