The Bush Business Furniture Bay Street Wingback Leather Office Chair presents a commercial quality workplace seating solution with new age contemporary style. Enjoy an upscale appearance and comfort to support you through a full workday as you tackle your next project at home or at the office. The tilt mechanism rocks back from a point over the center of the desk chair and can be set to a custom rate and ease of recline by turning the tension knob underneath the seat. A convenient lever instantly raises or lowers the seat's height to meet individual preference and is also used to lock the tilt function so it remains fixed in an upright position. Five dual-wheeled casters and a 360 degree swivel base provide complete mobility and range of motion throughout your workspace for effortless multitasking and collaboration. The mid back design promotes healthy posture to reduce strain and discomfort from spending long hours on the job, and winged sides on the seat and backrest add to the modern desk chair's sophisticated appearance. The heavy duty chrome base also gives the computer chair the strength to support up to 275 pounds while complementing your choice of Black, White, Dark Gray or Light Gray bonded leather upholstery options. This swivel chair with wheels has been tested to meet ANSI/BIFMA quality standards for safety and performance and is backed by the Bush Business Furniture 5 Year Manufacturer's Warranty.
