High-back swivel chair features a mesh back with a contemporary “Y” design that provides superior comfort with adjustable lumbar support and air circulation. The suspended seat contains bands of rubber embedded in high-density, highly resilient, molded foam that offers more comfort and support. Integrated seat slider lets you set the seat exactly where you want it. Two-paddle control provides one-touch, seat-height adjustment and five back-lock positions to adjust the chair to meet your specific preferences. Synchronized tilt control provides reduced, front edge rise while reclining. When desired, a convenient back lock prevents the back from reclining. Six-way arms move up and down; in and out; and forward and back for enhanced ergonomic support. Fiberglass-infused, reinforced nylon base with high-performance casters delivers strength, support and comfort. Weight capacity is 250 lb. Adjustable arms are sold separately. Chair exceeds ANSI/BIFMA standards and is Greenguard Certified.
