Cadeira de escritório TOPSTAR Open X N azul/preto

Office chair with point synchronous mechanism and height-adjustable armrests for dynamic sitting comfort.

Advantages

The TOPSTAR Open X N combines ergonomic support with durable materials.

The 100% polypropylene fabric upholstery is breathable, hard-wearing, and easy to clean. Double safety castors for carpeted floors ensure stable and quiet rolling. The safety gas spring (TÜV-tested) allows smooth seat height adjustment from 430 to 510 mm. Certified with the GS mark by LGA Nuremberg, this chair meets strict safety and quality standards.
