Office swivel chair Topstar Tec 50 — black, ergonomic design, height adjustable

Topstar Tec 50 is a black office swivel chair designed for desk work in home and corporate environments. The chair combines a compact ergonomic silhouette with height adjustment and a swivel base to support mobility and posture during prolonged sitting. Its neutral design integrates into standard office setups while providing basic ergonomic features intended to reduce strain during typical computer and administrative tasks.

Advantages

The Tec 50 offers adjustable seat height to align sitting position with desk height and monitor placement. Its swivel function enables easy reach across the workspace without frequent standing, and the contoured seat shell provides basic lumbar support to help maintain a healthier sitting posture. Constructed with easy-to-clean upholstery and a robust base, the chair is suitable for regular daily use and requires minimal maintenance.

• Home office work and remote desk tasks
• Corporate workplaces and meeting rooms

• Short- to medium-duration computer sessions

How to use

Adjust the seat height using the pneumatic lever so that your feet rest flat on the floor and your knees form approximately a 90° angle. Sit back to make contact with the contoured seat shell and position the chair so the lower back receives gentle support. Use the swivel function to turn across your workspace rather than twisting your torso. If the chair includes adjustable castors, choose suitable casters for your floor type to ensure smooth movement.

Usage recommendations

For healthier sitting, alternate between sitting and standing or short movement breaks every 30–60 minutes. Pair the Tec 50 with an ergonomically positioned desk and monitor: top of the monitor at eye level and forearms parallel to the desk surface. Regularly inspect castors and adjustment mechanisms and clean upholstery with manufacturer-recommended methods to maintain performance.
