Schäfer Shop Office chair SSI PROLINE S2, synchronous mechanism, without armrests, 3D mesh backrest...

The SSI PROLINE S2 office chair is a blessing for the back: With its special disc seat and the backrest featuring 3D mesh and synchronous mechanism, it supports dynamic sitting. This type of active sitting allows the seat and backrest to automatically adjust to changing sitting positions. With the synchronous mechanism, when leaning back, the backrest tilts first, followed by the seat slightly delayed. These constant changes in posture stimulate metabolism and supply muscles and intervertebral discs with oxygen. The mechanism can be precisely adjusted to the user's body weight and locked in multiple positions. Additionally, the PROLINE S2 office swivel chair features a disc seat with an elevated front edge and an integrated lumbar support in the backrest. These components protect your lumbar region by relieving the spine and bringing it into its natural S-shape. A comfortable knee roll provides extra seating comfort. The breathable 3D mesh fabric of the backrest further supports the back and provides secure hold during various movements. Moreover, the backrest is height-adjustable using a ratchet mechanism.
