This OfficeLounge Shell chair is one of the most rare Niko Kralj’s timeless classics besides the well known MOMA exhibited Rex item. Like all other Shells it’s made out of plywood, beech arms, and iron profile with a diameter of 17mm (0.67 inch). Seat height is 35.5cm. Reupholstered in quality leatherette used for yachts (UV protection, won't peel off), the frame has been sandblasted and powder-coated in original colour, arms have been lacquered. This piece has an attribution mark, I am sure that it is completely authentic and take full responsibility for any authenticity issues arising from misattribution
