## Long description

Topstar Sitness 228 is an ergonomic office chair with a round seat of 60 cm diameter and an overall height of 90 cm.

The model is suitable for office and home use and aims to increase comfort during extended periods of seated work.

Its 100% polyester upholstery is durable and easy to maintain, while the 60 cm wide seat provides a stable, ergonomic surface for different body types. The chair’s 90 cm overall height offers a compact profile suitable for standard desks and compact workspaces.

Overall height: 90 cm
Upholstery material: 100% polyester
Color: black
Ergonomic feature: dynamic/tilting seat mechanism for micro-movements

How to use
Adjust the chair into position so that your feet rest flat on the floor and your knees are roughly at a right angle. Sit centrally on the round seat to benefit from the dynamic tilt mechanism; allow small, natural movements to activate the seat’s mobility feature. Use with a desk set to a comfortable working height to maintain a neutral wrist and forearm position while typing or performing desk tasks.
Usage recommendations
Regularly change sitting positions during the day and take short breaks to stand or stretch. Keep the polyester upholstery clean by vacuuming and wiping with a damp cloth; avoid aggressive solvents. Pair the chair with an adjustable desk or footrest if you require additional ergonomic adjustments.
