This synchro mechanism add-on is for our PU chair. This add-on feature allows you to tilt the seat and back of the chair simultaneously. This is ideal for leaning over a bench, possibly when in a laboratory, as it allows you for permanent contact with your back, even if you lean forward!.

The function is controlled by a lever on the side of the chair, allowing easy customisation of your seating position. Moreover, the safety mechanism stops the chair hitting you in the back when the handle is released to be activated.
