The Hille ErgoStak chair is new for 2021. It achieves all the essential maintenance-free durability of an all-plastic chair, but it also responds to the demand for a sleeker, better-looking chair for new and future classrooms. In addition to its looks, ErgoStak has been designed to achieve much higher levels of ergonomic postural support than the existing all-plastic chairs on the market. This is a result of over 12 years of research and development (using Actiposture TM systems) and through finely tuned support of the pelvic/lower spine enables greater levels of student concentration UK Made and made in-house, which means its better value. Ergonomically better than anything out there. Sleeker with a more mature overall appearance. 10 year manufacturers guarantee Minimum order 15 chairs - Seat Width W482mm Free Delivery | Price Ex-Vat
