The Delta 135 Ratchet High Back Comfort Duo is a premium ergonomic task chair designed to deliver exceptional comfort, postural support, and long-lasting performance. Featuring the innovative Comfort Duo split-seat technology, this chair incorporates two independent zones of dual-density foam that have been recommended by medical practitioners to promote healthy sitting posture and reduce fatigue during extended periods of use.
The softer rear section allows the sitting bones to settle naturally into the seat, helping to minimise slouching and maintain proper spinal alignment. The firmer front section provides increased support beneath the thighs, encouraging improved blood circulation and reducing pressure on the legs. Combined with a ratchet-adjustable backrest and pronounced lumbar support, the Delta 135 offers personalised ergonomic comfort for a wide range of users.
