TOPSTAR Two 20 S100 sedia da ufficio ergonomica nero tessuto

The TOPSTAR Two 20 S100 is a high-quality office chair engineered for all-day comfort and reliable support. Its permanent contact mechanism synchronises seat and backrest movements, promoting a healthy, dynamic sitting posture during long working hours. The chair is upholstered in durable 100% polyester fabric in a timeless black, making it a versatile addition to any professional environment.

Advantages

The chair features height-adjustable T-armrests that relieve shoulder and neck tension, while the backrest adjusts in both height and tilt to suit individual preferences. A stepless gas spring allows precise seat height adjustment from 43 to 56 cm, accommodating various desk heights. Load-dependent braked double safety castors ensure stability on carpeted floors, preventing unintended rolling. Certified by TÜV Rheinland with the GS mark, it meets stringent safety and quality standards.
