Browse the our range of IOO High Back and IOOB Weight Balance Chairs. Designed and manufactured by the Team at Ergohuman, these Ergonomic Office Chairs benefit from the experience and expertise that goes into an Ergohuman Chair. A strong plastic frame rather than the cast Aluminium of an Ergohuman Chair sets the IOO range apart. The IOO High Back Chairs are lighter and benefit aesthetically from the white colour of the frame.  This creates a modern style in keeping with modern office technology and contrasts nicely with a choice of black, red or blue upholstery. For a straight forward and affordable option, the IOOB Weight Balance Chair is Classic Ergonomic Office Chair in black.
