The black and navy blue make a stunning combination on this iconic pair of lounge chairs. They were designed by the collaboration of Pratt Institute alumnus Bruce Hannah and Andrew Morrison for Knoll International, where they were both employed at the time. This award-winning and innovative aluminum-frame lounge seating system was introduced in 1971 and was purportedly inspired by the extruded aluminum of a sailboat mast. This pair have their original label underneath the seat and retain their original blue vinyl upholstery and black powder coat finish over their aluminum frame. I know you love this handsome pair. They should be yours.
