Active seat
Active seat

The seat cushion is actively varied by alternately raising and lowering the right and left half of the seat cushion. This reduces muscular tension and fatigue to help prevent lower back pain.

Press the button to switch on; the LED lights up.

The action of the system is reduced and if need be, switched off in order to reduce the load on the battery. The LED remains lit.

When the active seat is switched off, it can take up to 1 minute before the two halves of the seat cushion have returned to their initial position.
