The stylish and durable The Twillery Co. Custom Comfort Mesh High Back Task Chair provides all the adjustable features you need without the high-end price tag. Four easy-to-use levers instantly set the angle of the seat and back as well as the height and depth of the seat to accommodate all users. The backrest includes cushioned lumbar support and can easily be raised or lowered to meet your ergonomic preferences, and the high back design limits strain on the shoulders and neck for long-lasting comfort. Four-way adjustable armrests allow you to find the proper height, width, depth, and angle for your next project. The heavy-duty nylon base withstands years of use with a weight capacity of 275 pounds. This commercial-grade Ergonomic Office Chair is tested to meet ANSI/BIFMA quality standards for safety and performance and is backed by a 5-year warranty.
