This high-performance ergonomic office chair combines generous seating, advanced adjustability and responsive back support to create a personalized seating experience for long working hours. Its carefully considered design allows the chair to adapt to different body positions and working preferences.
COMFORTABLE SEATING
The spacious 520 mm wide seat features a 520 mm overall depth with 420 mm of usable seating depth. A gentle bend in the seat is designed to promote a comfortable sitting posture while helping reduce pressure on the thighs. The 80 mm thick foam cushion provides lasting comfort and support.
ADJUSTABLE SEAT HEIGHT
The seat height can be adjusted from 490 mm to 590 mm, allowing users to find a comfortable working position across different desk heights and seating preferences.
FLEXIBLE LUMBAR SUPPORT
The 620 mm high backrest provides extensive support for the upper and lower back, with a 493 mm width across the lumbar region. The lumbar support can be adjusted 40 mm up and down and is designed to flex with your body position, providing personalized support as you move.
ADJUSTABLE HEADREST
The headrest offers 20–60 mm of vertical adjustment along with swivel angle adjustment. This allows users to position the headrest according to their preferred posture and achieve more precise neck support.
ADJUSTABLE ARMRESTS
The armrests can be adjusted from 170 mm to 250 mm from the seat, providing flexibility for different users and working positions. Proper arm support helps create a more comfortable posture while working at a desk.
SYNCHRO MULTI-LOCKING MECHANISM
The synchronized mechanism allows the seat and backrest to move together naturally as you recline. Multiple locking positions and tension adjustment allow users to control their reclining movement and customize the chair to their preferred seating position.
