Designed to complement the Arne system, the J.J. Armchairs come in two different sizes: one for relaxing with a high backrest and a lower one for conversation. Two versions are available: with a chromed-plated steel rod frame or with made entirely of thermo-treated beech wood. The seat can be made of leather or pony skin and consists of tan, green or black criss-crossed bands and with a stretched cushion, attached to the frame. The version with a high backrest is also available with long-haired Mongolian goat fur, which can be applied to the leather upholstery.
