Sayl’s unframed 3D Intelligent back lets you stretch and move, striking a healthy balance between support and freedom and provides greater support in the transition areas
The construction of Sayl’s 3D Intelligent suspension back provides passive PostureFit sacral support, which allows your spine to maintain its natural S shape and empowers your body to maintain a healthful posture with less fatigue.
The foundational shell of the fully upholstered work chair mimics the 3D Intelligent suspension, providing similar dynamic support in a more traditional back. An optional lumbar support is available on both work chair models and provides adjustment over a 4-inch (10 cm) range.
