The Bush Business Furniture London High Back Leather Box Chair blurs the line between fashion and function to offer a refreshingly modern approach to office seating. Perfect for home and professional workspaces with contemporary style, this commercial-grade desk chair features a curved backrest that wraps around the body and tapers at the sides to support the elbows and forearms. The tilt mechanism rocks back from a point over the center of the chair and can be set to a custom rate and ease of recline by turning the tension knob located underneath the seat. A convenient lever instantly adjusts the seat height to meet individual preference and is also used to lock the tilt function so that the chair is fixed in an upright position. Five dual-wheeled casters and a 360 degree swivel base provide complete mobility and range of motion for multitasking and collaboration. Both the seat and backrest feature durable bonded leather upholstery, allowing you to work in comfort at home or at the office. The 17.9W x 18.7D seat is cushioned with foam padding to offer a medium-firm feel. A heavy duty chrome steel base supports the computer chair for a weight capacity of 275 pounds and offers a stylish complement to the upholstery. Choose from seven unique color options to find the perfect chair to coordinate with your workspace. This mid-century modern chair is tested to meet ANSI/BIFMA quality standards for safety and performance and is backed by the Bush Business Furniture 5 Year Warranty.
