With its contemporary style and commercial quality design, the Bush Business Furniture Move 60 Series Mid Back Leather Office Chair is a perfect choice for use in any home or professional workspace. Get to work on your next project or assignment from the comfort of a swivel chair that adjusts to your own preferences quickly and easily. The tilt mechanism can be set to a custom rate and ease of recline by turning the tension knob located underneath the seat. A convenient lever instantly raises or lowers the seat's height and is also used to lock the tilt function so that the computer chair remains fixed in an upright position. Armrests are vertically and horizontally adjustable to support your elbows and forearms in a way that allows you to type, write or craft comfortably. Five dual-wheeled casters and a 360 degree swivel base provide complete mobility and range of motion for multitasking and collaboration. The 20.7W x 18.5D seat features medium-firm foam cushioning while the backrest is ergonomically contoured to help avoid strain and discomfort during long days on the job. A heavy duty Chrome base supports the office chair with wheels for a weight capacity of 275 pounds and offers a stylish complement to the bonded leather upholstery. This computer desk chair 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.
