The Java 300 Medium Back Synchronous Operator Chair is a robust and highly adjustable ergonomic task chair designed to support comfort and productivity in demanding office environments. Engineered for reliable daily use, it combines advanced functionality with a practical, professional design.

Its posture-curved seat features a waterfall front edge that helps reduce pressure on the thighs and supports healthy circulation during long periods of sitting. An under-seat skirt provides a clean, refined finish, while the contoured medium backrest is sculpted with integrated lumbar support to encourage correct spinal alignment and reduce fatigue.

The chair is equipped with a triple lever synchronous mechanism, offering enhanced control over seating posture. Users benefit from independent seat tilt alongside synchronised back movement, allowing for a tailored and supportive seating experience. Additional ergonomic adjustments include back height, back rake, and back tilt functionality for precise positioning.

A durable gas lift ensures smooth seat height adjustment, while adjustable armrests provide adaptable upper-body support to suit different users and workstation setups. Finished with a sturdy black five-star base, the Java 300 is also certified to BS EN 1335 Level 3, confirming its compliance with recognised ergonomic and safety standards.
