This is a left/right set of fixed-height Remastered Aeron armrests with armpads in the mineral colorway. These were removed from a 2018 Aeron Remastered (Mineral) and are in good overall condition, with normal cosmetic wear (scuffs/scratches). These are the fixed-height (“static”) arms, meaning. Arm height is set during installation. After installation, the height does not adjust via a lever/knob. Height can still be changed, but you must remove the backrest to do it. Best match: Aeron Remastered in Mineral. Also compatible with Classic Aeron: These will bolt up to a Classic Aeron, but on some chairs, you may need to remove a plastic trim piece in the swing arm to make clearance. That trim piece is cosmetic only (no functional role). Classic Aeron’s did not come in the Mineral colorway, so if you install these on a Classic Aeron, expect a color mismatch.
