The About collection is the most flexible collection of furniture from HAY. It began with a chair and flourished into a quasi-unlimited potential sequence. This iteration of About a Chair is height-adjustable because there is a semi-automatic gas lift on the five-legged platform. As the conventional office chair it is, the latest aluminum frame has castors and the adjustable seat height ranges from 42 cm to 56 cm. A chair with gas lift is accessible with the original, open seat or rounded shell as is the case with the other variants Of a Chair.
