Mid-Back Ergonomic Design Built for Daily Performance
Not every workspace needs a full high-back executive chair. The Hartley Task Medium Mesh Back Chair provides a more compact, open feel while delivering targeted ergonomic support where you need it most. Featuring a high-tension black Promeshâ„¢ backrest (490mm height), it promotes active airflow to keep you cool, paired with a high-resilience molded foam seat pan (500mm W x 480mm D) that cushions pressure points during long working sessions.
Synchro Mechanism & Intuitive Adjustment
Stay comfortable as your posture shifts from task to task. The integrated synchro mechanism synchronises the tilt of the backrest and seat pan, providing fluid movement that supports your spine through dynamic workdays:
- Synchronised Tilt & Gas Lift: Smoothly recline while keeping your feet planted, with a gas-lift seat height adjustment range of 440mm to 520mm.
Independent Back & Seat Pan Tilt: Fine-tune the angle of the seat and backrest individually to lock in your preferred posture for typing, reading, or collaborative meetings. - Included Adjustable & Removable Arms: Easily adjust armrest height to align with your desk surface, or remove them completely for tight clearance requirements or specific task freedom.
