Managerial Mid-Back Chair for Office Use

The Lorell 86904 is a managerial mid-back chair designed with a mesh back and seat for breathable comfort. Its ergonomic shape matches the natural curvature of the back to support posture during long work sessions. The chair features a five-star nylon base and meets the CA117 fire-retardant standard for safety compliance. It is sold as a single unit in a black frame finish.

Suits Adjustable Seating Needs.

This chair suits users who require a highly adjustable seat with pneumatic height adjustment ranging from 17 to 21 inches from the floor. Arms adjust in both height and width, while back-height adjustment and asynchronous three-lever control allow precise tilt and recline tuning. The 360-degree swivel adds mobility. Buyers needing a weight capacity above 250 lb should consider alternative seating options.

Mesh Upholstery and Durability Rating Define Daily

The mesh back and seat promote airflow to reduce heat buildup during extended sitting periods. An abrasion rating of 60,000 double rubs per ASTM-D-4175 indicates high resistance to wear from daily friction. The CA117 compliance confirms the materials meet specific fire-retardant requirements. These attributes combine to deliver a durable, breathable seating surface for managerial environments.

Questions about this item

Does the chair arrive fully assembled or will I need tools to attach the five-star nylon base?

The chair is sold as one unit; the five-star nylon base, pneumatic cylinder and casters must be assembled on site with basic hand tools.

Can the 17 to 21 inch pneumatic seat-height range match my existing desk height?

The pneumatic lift adjusts the seat from 17 to 21 inches off the floor, so measure your desk clearance to confirm a comfortable fit.

How do I verify the asynchronous three-lever control is operating correctly after assembly?

Sit in the chair and test each lever independently — seat height, back height and tilt tension should each move smoothly without binding.
