Product information

This office chair guarantees you will sit comfortably throughout the working day thanks to the asynchronous mechanism that enables you to fix or free float the tilt of the back and seat independently of each other, helping you to vary your posture and find the most comfortable position. A torsion control function means that you can also change the ease with which the chair position moves to suit your body weight. Furthermore, the lumbar pump lets you adjust the level of back support to your needs, helping to prevent or alleviate back problems, while the waterfall seat and adjustable seat slide help to improve circulation in your lower legs. The back can also be adjusted in height.

Upholstered in blue or charcoal fabric, the office chair comes with gas height adjustment and a black, nylon 5-star base. The foam in the back and seat is rated for fire retardancy to BS 5852 and the upholstery to BS 7176 medium hazard. The chair has a recommended usage time of 8 hours, with an 18 stone (115 kg) maximum weight capacity, and fixed or adjustable armrests are available as optional accessories.

Don’t forget to add a chair mat to protect the floor or carpet from wear and tear.
