The La-Z-Boy Cantania Executive Office Chair - Coffee uses AIR lumbar technology with a pivoting design to improve posture and reduce discomfort, all while enhancing breathability and air flow, too. The waterfall seat edge helps promote leg circulation, while ComfortCore Plus memory foam, complete with a poly-fiber top layer, offer the coziest work day you've ever had. The hand-sculpted metallic arms are finished in a moonshine color, a perfect pairing for the coffee-colored bonded leather upholstery. Approved by the American Chiropractic Association.
