X4 leather executive chair by X-Chair

Beltsville, Md.-based seating manufacturer X-Chair has launched the X4 leather executive chair.

X4 uses proprietary "SciFloat Infinite Recline" technology, which works to keep the user in motion throughout the day, while its "Dynamic Variable Lumbar" support adjusts to the body’s every move, so the user can maintain comfort without making a single adjustment.

The X4 is available in brown, cognac and black leather. Additional features include adjustable seat height, adjustable seat depth, tilt tension and tilt lock, height-adjustable backrest, four-dimensional arms, and adjustable headrest angle.
