Charles Pollock armchair

Charles pollock (1930-2013) Office chair model "executive chair" adjustable in height. The height adjustment is done by disassembling the foot, this is the disadvantage. A faith settled, the foot goes up with its 4 screws and it is settled. A leather restoration was done by an upholsterer on an 8mm hole on the seat. See photo. Edition knoll 1970s. The inner foams remained firm. That's knoll quality! Chrome base first editions with 4 branches. Shells molded by thermoforming. H seated from 39 to 45 cm.
