The AAC 155 Soft counterbalances the high functionality and modern expression of the task chair’s castor base with the softness and warmth of the quilted shell. Retaining the same high backrest and generous seat that characterises the series, the base is designed with a tilting mechanism and a gas lift that can adjust the seat height. The base is available in polished or powder-coated aluminium, and the quilted shell is offered in a variety of upholstery options, providing a multitude of design combinations that give this series versatility in a wide range of corporate, public, and private contexts.
