With our heavy duty chairs we don't hide behind details you need to know. Most office chairs have a weight tolerance of 16 st. (102 Kgs) and for a maximum use of 8 hours per day, with our durable big chair range you can be assured that the chairs are weight rated to a minimum of 24 st (152 Kgs) and are upholstered in a durable chair fabric from leading UK suppliers. We also ensure that our heavy duty chairs incorporate high grade durable foam, the last thing you need is foam that turns to dust after 12 months. More importantly several of our large chairs have coil sprung seats and backs that evenly distribute your body weight and have many benefits over a foam only chair. In addition these large chairs can be upgraded to incorporate "coil plus" springs to increase the weight tolerance to plus 30 st (191 Kgs).
