The Aston executive chair, with distinctive design and balanced proportions, is ideal for offices and executive meeting rooms. By Arper, the executive collection is distinguished by 3 heights of the chair back - low, medium and high - all with steel frame and injection-moulded foam, upholstered in a choice of house fabrics or leather. The polished aluminium five-star base includes castors and a gas-operated height adjustment, together with a spring mechanism to provide an element of tilt. A castor chair with synchro mechanism in high and low back versions of the Aston is also available.
