We have just a couple left of these Herman Miller Ergons that we have reupholstered in black vinyl. This is the original style of chair that Herman Miller had made by the famous designer Stumpf, who also designed the Equa and Aeron chairs for Herman Miller. They are swivel/tilt, with one-touch gas lift, and adjustable height arms, and tension control. The bases and arms are also black, and these chairs look great. They are perfect for sales, management, and conference uses. We are selling them for $169 each. We have around 20 available in original very used condition for reupholstery in any color as well. Please email or call us for reupholstery details and pricing.
