ActiveJet YK507 black is a swivel ergonomic task chair designed for everyday desk work in home offices and professional workplaces. The chair combines a padded seat and back covered with fabric and PU to balance comfort and easy maintenance. A pneumatic height adjustment allows users to set a suitable seating position, while a five-star base with casters provides stable mobility across typical office floors.

Advantages

The YK507 offers a compact ergonomic profile with padded upholstery that supports prolonged seated tasks without complex adjustment mechanisms. Fabric and PU materials give a practical surface that is comfortable to the touch and simple to wipe clean. Its pneumatic height adjustment and swivel base enable quick position changes and easy access to surrounding work areas.

Suitable for

When it may not be suitable

This chair provides basic ergonomic support but lacks advanced adjustable features such as lumbar tuning, seat depth adjustment or multi-tilt mechanisms. Users requiring targeted lumbar support, full recline functions, or heavy-duty seating for extended eight-plus hour shifts may find a higher-spec ergonomic model more appropriate.

Key specifications

How to use

Adjust the seat height using the pneumatic lever so your feet rest flat on the floor and your knees are at approximately a 90° angle. Use the swivel function to reach items around your desk without twisting your torso. Roll the chair on appropriate floor surfaces with the casters and avoid dragging the chair across rough or uneven flooring to preserve wheel function. For cleaning, wipe PU areas with a damp cloth and treat fabric areas according to fabric care guidelines to avoid moisture damage.

What to consider before purchase

Recommendations

For improved comfort during extended use, pair the chair with an adjustable desk and adopt regular posture breaks. Maintain a neutral spine, and set monitor height so the top of the screen is at or slightly below eye level.
