Contemporary swivel stool features a unique mesh back that provides superior comfort and support by flexing with your movements while providing lumbar support and air circulation. The air-grid seat fabric allows healthy airflow while the high-density molded foam offers more comfort and support. This highly resilient foam will maintain its shape far longer than conventional cut foam. A pneumatic cylinder provides one-touch, seat-height adjustment while height-adjustable arms, adjustable tilt tension and back-depth adjustment let you adjust the chair to meet your specific preferences. Synchronized tilt control provides reduced front edge rise while reclining, and a convenient back lock prevents the back from reclining when desired. Soft-touch armrest pads provide comfort and protection for desks or tables. Fiberglass-infused, reinforced nylon base with high-performance casters delivers strength, support and comfort. Weight capacity is 250 lb.
