Office chair Topstar Point 91 — ergonomic design, adjustable height, black

The Topstar Point 91 office chair provides ergonomic support for extended sitting. It features a high, orthopedically shaped backrest with side padding to stabilise the back and a large, wide contoured seat with lateral padding to secure the sitter. The chair includes a point-synchronised mechanism with safety release that allows synchronous adjustment of seat and backrest tilt; these movements can be locked in multiple positions and adapt to body weight. The chair stands on a polished aluminium base with a 64.0 cm diameter and rolls on double casters suitable for soft floors. Upholstery is 100% polyester in black and the seat height is adjustable.

Advantages

The high orthopaedic backrest and contoured mulden seat reduce pressure points and support upright posture. The point-synchronised mechanism with safety release enables smooth, coordinated seat and back adjustments and multiple locking positions for personalised ergonomics. Durable aluminium base and double rollers for soft floors provide stability and mobility. The black polyester cover is easy to maintain and matches various interiors.

How to use

Sit with your back against the high backrest so the side padding stabilises the torso. Adjust seat height until your feet rest flat on the floor and your knees are approximately at a right angle. Use the mechanism controls to set the synchronous tilt of seat and backrest; lock the preferred position using the multi-position arrest. Slide the seat if needed to optimise thigh support. Move the chair using the double rollers suitable for soft floors.

Usage recommendations

For comfortable long-term use, periodically adjust tilt and seat height to vary posture, and check caster suitability if used on hard floors—replace with hard-floor casters if necessary.
