The Sayl Office Chair by Herman Miller is an ergonomic, innovative, and cost-efficient seating solution that rivals higher-end models in adjustability, quality, and orthopedic performance.
This version features a medium-height backrest and the signature frameless 3D Intelligent back, which provides continuous support while allowing complete freedom of movement.
The lumbar support is independently mounted and can be adjusted within a 10 cm range, letting you fine-tune it for your body’s natural curvature. The seat’s polymer mesh upholstery is made of fibers of varying height and thickness, which flex freely to deliver full postural support and balanced comfort throughout the day.


The polymer mesh upholstery is a practical and durable surface that doesn’t deform, crack, or collect dust, and resists visible wear over time. The elastomer-infused fibers flex naturally to contour the body, yet instantly return to their original shape after use — ensuring lasting comfort and resilience.
The innovative Y-Tower™ mechanism features a precisely engineered point-support structure distributed across the entire backrest surface. This design provides targeted spinal support when reclining, maintaining natural posture and comfort while promoting healthy back alignment throughout the day.


The outer lever controls the forward tilt, while the inner lever adjusts the backward recline.
For optimal ergonomic posture, the forward tilt angle should be set between 7–10 degrees, helping you maintain active sitting during focused work.
You can also fine-tune the tilt limiter using the horizontal lever located on the left side beneath the seat — allowing you to set and lock the recline at your preferred level for balanced comfort and posture support.
Adjustable Seat Height and DepthThe Sayl Chair allows precise customization of seat height and depth using the lever on the right side, located next to the tilt tension control.
To raise the seat, stand up slightly and lift the lever upward.
To lower it, lift the lever while seated — your weight will bring it down smoothly.
The optimal ergonomic position is achieved when your feet rest flat on the floor and your knees form a 90-degree angle.
To adjust the seat depth, slide the seat forward or backward to find your perfect sitting position. The correct depth provides about three fingers’ width of space between the back of your knees and the front edge of the seat — ensuring healthy circulation and lasting comfort.
