TOPSTAR Sitness AirWork G Silla de oficina ergonómica, tejido gris, estructura negra PA40OMT3MT3

The TOPSTAR Sitness AirWork G PA40OMT3MT3 redefines active sitting with its synchronous mechanism and individually adjustable backrest, setting it apart from conventional office chairs that force a static posture. This model encourages continuous micro-movements throughout the workday, promoting spinal health and reducing fatigue even during extended use.

Highlights

• Breathable mesh backrest with integrated, adjustable lumbar support for tailored lower back relief.
• Synchronous mechanism with individual weight adjustment for seamless recline and optimal support.
• Height-adjustable T-armrests and sliding seat depth adjustment for personalized comfort.
• Robust polyamide star base with brake-controlled double safety casters, ideal for carpeted floors.
• GS-tested (TÜV Rheinland) and EN 1335 certified for safety and durability up to 120 kg.

In daily use

From the first sit, the AirWork G adapts to your body. The stepless gas lift adjusts seat height from 43 to 51 cm, while the sliding seat lets you fine-tune depth for proper thigh support. The backrest height is also steplessly adjustable, ensuring the lumbar pad aligns perfectly with your spine. The synchronous mechanism allows the backrest and seat to move in a coordinated ratio, keeping your feet grounded and your back supported as you recline. The mesh fabric promotes airflow, preventing heat buildup during long sessions. The T-armrests can be set to the ideal height to reduce shoulder tension, and the brake-controlled casters keep the chair stable when you need to stay put.
