These ergonomic office chairs are ideal for demanding work environments such as call centres and control rooms that are open 24/7. They are certified by FIRA to BS EN 5459-2:2000, meaning they are structurally suitable and sufficiently stable for 24-hour contract use for people weighing up to 24 stone (150 kg). Thanks to the heavy-duty asynchronous mechanism, you can adjust the tilt of the back and seat independently of each other, change the height of the backrest and move the seat up or down – all of which help you to vary your posture and find the most comfortable position. For even more comfort, the 24-hour chairs come with height- and width-adjustable armrests. The foam in the seat and back is rated to BS 5852 and the fabric upholstery to BS 7176 medium hazard for fire retardancy. A black, nylon 5-star base is fitted as standard, but you can choose to purchase a polished aluminium base separately – see accessories.

Don’t forget to add a chair mat to protect the floor or carpet from wear and tear. For a completely ergonomic solution you may want to consider adding a footrest to support your lower legs or even purchasing a height-adjustable desk to allow you to sit or stand as you prefer.
