High-back mesh chair with adjustable headrest, 3D armrests and ergonomic S-shaped back. Gas lift is BIFMA and SGS certified and rated to bear up to 330 lbs (23.57 st).
Spine-friendly support – with S-shaped backrest and adjustable headrest
S-shaped backrest copies the natural curve of the spine, while an adjustable headrest and lumbar arrangement allow personalised alignment. The mechanism supports reclining to three preset angles, recorded at 110°, 116° and 126°.
Consistent spinal alignment and neck support reduce strain during extended sitting, helping maintain focus and comfort through long sessions.
Flexible arm support – with 3D adjustable armrests
Armrests adjust in five height positions, slide forward and back, and rotate side to side, with a PU leather surface for a comfortable resting area. Multi-axis movement lets hands and forearms find a natural position for different tasks.
Multi-angle support helps keep shoulders relaxed during typing, gaming or streaming, reducing tension over time.
Cool, supportive seating – with breathable mesh and springy foam
Polyester mesh on the seat and back promotes airflow, while springy foam at the seat front and a curved profile deliver targeted support where the legs and pelvis need it most.
Breathable materials and a supportive cushion prevent overheating and the feeling of sinking, keeping posture stable for longer periods.
