AS-stools are provided with back to front swivel backrest supports, while the OP-stools are equipped with adjustable, contoured backrests that have been anatomically designed to fit your back and ensure maximum comfort during use.

All models are pneumatically operated, with an adjustable height range.

The radial base has silent, robust castors and is covered with a special shock-resistant protection for Spider models or in polished aluminum metal (easy-to-clean and always shiny!) for Andy models. Foot-ring supports are also available.
