The iconic office chair series from which this Kardiel Lider Mid Back reproduction takes its inspiration was originally developed in 1958. The seat and back rest is made of a continuous single section of Commercial grade leatherette upholstery stretched taut between two metal ribs. This allows it to subtly conform to the shape of the user’s body and makes it comfortable for long periods of sitting. This series was originally know as the Aluminum Series for good reason. This reproduction frame is made of polished aluminum in keeping with the original appearance intent of the design. This is a departure from the chromed metal used often on reproductions. None of the details were overlooked, from the distance of the ribbed stitching to the period correct Atomic metal ball of the height adjusting lever.
