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