Sayl - office chair, green carcas, green seat, on castors

The Sayl Office Chair by Herman Miller is the most budget-friendly option in the lineup — yet it rivals more expensive models in both adjustability, quality, and ergonomic performance.

Its innovative Y-Tower™ structure connects the seat and backrest, forming a flexible frame that adapts perfectly to the user’s posture. The lumbar support is independently mounted and can be adjusted within a 10 cm range, allowing precise customization for your back.

The frameless 3D intelligent suspension back provides exceptional support while allowing complete freedom of movement — ensuring you stay comfortable, active, and well-supported throughout the day.

Specifications

Seat Base — Polymer Mesh

The seat base is made of a polymer mesh with elastomeric fibers that flex naturally around the body without losing shape. This innovative material combines strength, elasticity, and durability, providing ergonomic comfort and long-lasting performance.

The mesh maintains its original form over time — it doesn’t stretch, crack, or trap dust, and remains smooth and clean even after years of use. This makes the Sayl Chair both a practical and elegant solution for modern workspaces.

Back Support That Adapts to You
The Sayl Chair features the innovative Y-Tower™ support system, which acts as the backbone of the chair’s design. Its 3D suspension structure, distributed across the entire backrest, provides precise, responsive support to your spine — especially when reclining — ensuring natural posture and comfort throughout the day.

Frameless 3D Intelligent Suspension
The frameless 3D Intelligent back fully supports your body while allowing complete freedom of movement. This advanced engineering enhances support in the sacral and lumbar regions while maintaining balanced pressure along the entire spine, helping you stay active and comfortable no matter how long you sit.

Smooth Recline and Motion Support
The Sayl Chair features a gentle, balanced rocking motion that promotes healthy circulation and provides a subtle orthopedic effect. This natural movement helps prevent stiffness and fatigue, allowing you to stay relaxed and focused even after long hours of work.

Adjustable Armrests — Height, Depth, and Angle
The armrests can be adjusted vertically by more than 10 cm, and moved forward or backward for optimal alignment with your desk. When positioned at the same height as the tabletop, your elbows remain supported — reducing strain on your forearms and wrists.
You can also adjust the width and rotation of the armrests, ensuring personalized comfort and proper ergonomic positioning while typing or using a mouse.

Adjustable Seat Height and Depth
The Sayl Chair allows you to fine-tune both the height and depth of the seat using the lever located on the right side of the chair, next to the tilt tension control.

• To raise the seat, stand up slightly and lift the lever upward.

• To lower the seat, lift the lever while sitting — your weight will bring it down smoothly.
  The optimal height 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 until you find your most comfortable position. Ideally, there should be about three fingers’ width of space between the back of your knees and the front edge of the seat — ensuring proper circulation and long-term comfort.

Adjustable Tilt Tension
You can fine-tune the backrest tension by turning the knob on the right side of the chair. Rotate it to increase or decrease the level of resistance, depending on your comfort preference.

The goal is to find a balance where the chair reclines smoothly without excessive effort, yet the backrest doesn’t “give way” — maintaining proper support and natural body alignment while you move.

Forward / Backward Tilt Adjustment
The backrest tilt of the Sayl Chair can be customized using the levers on the left side of the chair.

The outer lever controls the forward tilt, while the inner lever adjusts the recline backward.
For optimal ergonomic posture, the forward tilt angle should be around 7–10 degrees, helping you maintain active sitting during focused tasks.
You can also set the tilt limiter using the horizontal lever on the left side under the seat — allowing you to lock the recline at your preferred angle.

Additional Lumbar Support
Extra lumbar support is provided through an adjustable lever and lumbar pad located on the back of the chair. Move the pad forward or backward to fine-tune its position so that it comfortably supports the natural curve of your spine.

Floor-Friendly Casters
The Sayl Chair comes with rubberized casters designed for hard flooring. They glide smoothly, don’t scratch the surface, and leave no marks, ensuring effortless mobility and lasting floor protection.
