Featuring a swivel base in aluminium, the AAC 220 has a slightly more formal expression than the other variants in the series. Retaining the fundamental idea shared by the AAC collection, this model is characterised by a curved shell with a slightly higher back. Designed with optimal functionality in mind, the shell construction offers a deep, generous seat that combines inviting aesthetics with a high level of comfort, whilst the lower armrests provide good support and enable the chair to fit underneath a table or desk. The base is available in either polished or powdercoated aluminium, with the post-consumer recycled plastic shell offered in a wide palette of contemporary colours and multiple front upholstery options. The multitude of variants and design combinations give this series a versatile expression that makes it suitable for a wide variety of corporate, private, and public contexts.
