About this Chair

The Proform Diamond executive office chair is made with genuine Italian leather and ergonomic features. The beautiful design incorporates hand-crafted diamond stitching details on the front and back of the chair.

Cushion is constructed with ergonomic proprietary foam technology. The closed-cell, cold-cured foam is designed to provide body-cradling and balancing support where needed with softer edges to alleviate pressure points and improve circulation when sitting for extended periods of time.

Body-balanced control automatically adjusts to your body weight and provides intuitive movement.

Height-adjustable back allows for comfortable lumbar positioning.

Polished aluminum frame curves and contours to support the lumbar area.

Hand-crafted stitching and Italian leather work seamlessly in any office environment.
