Perhaps the most functional chair of the series, the About A Chair AAC53 features a five-legged castor base equipped with a semi-automatic gas lift that can adjust the seat height from 42 to 56 cm. Just like the rest of the series, the aluminium base can be combined with the original, open seat or rounded shell to make the look as formal or relaxed as you like. A wide choice of colours and fabrics give you further options to adapt the chair to whatever environment you need.
