Pro Line II High Back Ergonomic Mesh Office Chair [90662-30]
The ProGrid screen mesh backrest is designed to provide optimal ventilation while delivering excellent lumbar support, ensuring comfort throughout extended periods of sitting. The seat is thickly padded with high-density molded foam, offering a plush yet supportive surface that contours to the body.
Featuring a sophisticated 2-to-1 synchro tilt mechanism, this chair allows users to recline while maintaining a stable seat position, keeping the seat cushion relatively level with the ground for enhanced ergonomics. The tilt lock function allows for customizable seating positions, and the tilt tension adjustment enables users to easily modify the resistance of the recline to match their preferences.
To accommodate various body types and sitting styles, the chair includes a seat slider, enabling users to adjust the seat depth for maximum comfort. Pneumatic controls allow for easy adjustment of the seat height, allowing users to find the ideal position relative to their workspace.
The built-in lumbar support is thoughtfully designed to promote proper spinal alignment, reducing the risk of back strain during long hours of work. The chair offers a full 360-degree swivel capability, allowing for fluid movement and easy access to different areas of your workspace.
Additionally, the height and width adjustable arms come equipped with urethane pads for added comfort and support, reducing pressure on the shoulders. Finally, the heavy-duty five-star base is complemented by dual wheel casters, providing stability and mobility across different floor surfaces.
