The AAC 153 Soft Duo counterbalances its soft quilted shell and contrasting materials with the high functionality and modern expression of the five-legged castor base. Retaining the same high backrest and generous seat that characterises the series, the base is designed with a gas lift that can adjust the seat height by a range of 14cm. The base is available in polished or powder-coated aluminium, and the quilted shell is offered with two different textiles or leathers to create a unique look that works equally well in corporate, public, or private contexts.
