The Harmony Chair by Longhi consists of two finishes: The backrest structure is in iron and cold moulded polyurethane foam. The seat base is in wood with elastic bands covered in multi-thickness polyurethane foam. The upholstery is glued to the frame and therefore non-removable. Four toe caps in bronze coloured PLA can be inserted to protect the leather that covers the bottom of the leg. They are simple to insert and remove if needed, and form the perfect base for the shape of the chair leg.
