RH Chairs has launched its new Activ chair, a mainstream office chair that does not compromise on ergonomics, environmental credentials or quality. The chairs mechanism is based on the principle of active sitting, encouraging people to move throughout the day, improving comfort, well-being and productivity, as well as developing core stability. It also meets the requirements of the Environmental Product Declaration and has a ten year warranty, as do all RH products.www.rhchairs.co.uk
