Take a Seat
Forklift drivers often do not work in the best of environments. And safety is of utmost priority.
Most people pay attention to other parts of a forklift, e.g mast, brakes, etc but not the seat (unfortunately).
Have a heart. Get a comfy seat for your drivers. It delivers comfort and increases productivity, while indirectly enhances their focus which also influences safety.
Are forklift seats expensive? Not at all. The cost depends on the seat configuration and spec. Whatever it is, the cost is definitely affordable.
