TOPSTAR Two 20 S100 ergonomische bureaustoel zwart stof

The TOPSTAR Two 20 S100 is a high-quality office chair engineered for all-day comfort and reliable support.

The chair is upholstered in durable 100% polyester fabric in a timeless black, making it a versatile addition to any professional environment.

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.
