With a comfortable design and plenty of adjustable features, the Bush Business Furniture Corporate Mid Back Multifunction Mesh Office Chair offers an ideal seating solution for any professional environment at an affordable price. Four easy-to-use levers instantly change the angle of the seat and back as well as the height and depth of the seat to accommodate users of all shapes and sizes. The contoured back adjusts up and down separate from the rest of the chair to provide the proper ergonomic support for the mid to upper back, keeping you comfortable through a long day at the office or when working on a project at home. A knob underneath the seat turns to set the amount of tension felt when leaning back, and the polypropylene armrests are also height adjustable and feature soft padding for flexible comfort. Five dual-wheeled casters allow the chair to roll freely throughout your workspace while 360 degree swivel control provides full range of motion. The heavy duty nylon base withstands years of use and allows the computer chair to support up to 275 pounds. Both the seat and back feature lightweight, breathable mesh upholstery for a modern look that works well in home or professional offices. The commercial-grade Mid Back Multifunction Mesh Office Chair is tested to meet ANSI/BIFMA quality standards for safety and performance and is backed by the Bush Business Furniture 5 Year Manufacturer's Warranty.
