A 12 cm sliding range helps users position the headrest at the right height. The pivot joint also adjusts the support angle for better head and neck comfort.
The integrated coat hanger keeps jackets neat and within reach.
The zoned mesh back follows the natural curves of the upper and lower back. Users can adjust the backrest through three positions across a 9 cm range, with pull-up reset at the highest point.
A reinforced nylon composite frame adds strength, while the rear cover provides space for a custom logo.
Two wide lumbar wings provide fuller, more balanced support.
The entire waist module provides full, adaptive support on its own. Two additional springs behind each pad add flexible feedback, allowing the lumbar support to follow subtle posture changes.
Wide, soft PU pads keep the arms comfortably supported.
The seat-mounted design offers height and forward-backward adjustment, 360° upper rotation, 270° lower rotation, inward-outward positioning, and an upward-tilting arm pad.
The cable-control unit puts key adjustments within easy reach.
Users can change seat height, slide the seat forward by up to 5 cm, and lock the recline in four positions without bending down. The backrest reclines up to 145°, while a lower knob controls tilt tension.
A Class 4 gas lift provides a 100 mm adjustment range for smooth, reliable seat-height control.
The one-piece aluminium base uses strong 350 mm square-tube legs. It withstands a 1,136 kg static load test and a 136 kg impact test for dependable daily use.
The 60 mm PU casters roll quietly while helping absorb vibration. They have passed BIFMA X5.1 testing and are available in black or grey.
The dual-rail mesh leg rest pulls out smoothly when users want extra support.
The chair frame uses virgin nylon plastic reinforced with glass fibre. This combination provides high strength, good toughness, and better resistance to ageing.
The black or grey elastomer mesh feels smooth rather than coarse. It maintains support after 100,000 impact cycles, helping the seat and back resist sagging over time.
