The Flash Furniture office swivel chair in black with LeatherSoft upholstery is an ergonomic work chair designed for comfort and support during long work sessions. The mid-height back profile provides targeted support in the mid to upper back area and helps maintain proper posture. The chair is upholstered in durable black LeatherSoft material, which offers a soft yet resilient surface for daily use. Key adjustable features include a pneumatic seat height adjustment, allowing users to set the seat height to their preferred position, and a lockable synchronous tilt function that allows the back and seat to tilt backward at different speeds, increasing the angle between the upper body and thighs for enhanced comfort. Additionally, a lockable back angle adjuster allows for adjustments to the upper body angle to reduce pressure on the intervertebral discs. The contoured seat with a waterfall front edge helps distribute pressure points and relieve pressure from the lower legs, improving circulation.
