TOPSTAR bureaustoel met synchroonmechanisme, zwart/petrol

An ergonomic office swivel chair engineered for dynamic, all-day sitting. The TOPSTAR PA20OMP0CX6 combines a synchronous mechanism with Sitness-Gelenk 3D active sitting technology to promote natural movement and core engagement while you work. The black and petrol fabric upholstery offers a modern look that fits any professional environment.

Advantages

The synchronous mechanism synchronises the seat and backrest movement, providing continuous support as you recline. The Sitness-Gelenk joint allows the seat to tilt in all directions, activating your back muscles and improving posture.

The polished aluminium base and load-dependent braked castors deliver stability and safety on carpeted floors.
