## Long description

Topstar Sitness 10 — ergonomic seating in blue designed for everyday desk work. This office chair combines a supportive shell with a flexible sitness mechanism that promotes active sitting and small posture adjustments. Adjustable height allows correct alignment with desks of different heights, and the seat construction is intended to reduce static load during prolonged use. The blue finish offers a neutral yet distinct appearance suitable for home offices and corporate environments.
Advantages

Height adjustability ensures ergonomic positioning of hips and knees relative to the work surface. The chair’s compact footprint and lightweight construction make it easy to move between rooms. Materials are chosen for daily use to support frequent sitting without complex adjustments.

Key specifications
 Type: Ergonomic office chair with sitness mechanism
 Color: Blue
 Seat: Molded supportive seat shell designed for dynamic sitting
 Height adjustment: Gas lift for seat height adjustment
 Base: Five-star base for stability
 Usage: Intended for daily desk sitting and moderate-duration use
How to use
Adjust the seat height so that your feet rest flat on the floor and your knees form approximately a right angle. Sit with your back against the seat shell and allow the sitness mechanism to follow small shifts in posture; avoid locking in a single rigid position for long periods. Use the chair on a flat, stable floor surface and ensure the five-star base is unobstructed for free caster movement. For cleaning, follow material-appropriate care: wipe smooth surfaces with a damp cloth and avoid aggressive chemicals.
Usage recommendations
For best ergonomic effect, combine the chair with a desk at a suitable height, take regular short breaks to stand and stretch, and alternate between sitting positions to maintain circulation and reduce discomfort during extended work sessions.
