Since the seat uses a hard and thick cushioning material, there is little sinking of the body, which helps with reducing tiredness even after long-term use.
The seat is of unique triangle shape which reduces the pressure on the rear thighs.
The backrest, which has been devised in the width and curvature that holds the upper part of the waist, not only receives the back, but also has the effect of maintaining a posture that can reduce the burden on the operator’s waist.

The foot-operated lift unit inherits the simple and highly durable
mechanism from the previous model, and the foot pedal allows
to perform easy and reliable lifting/lowering/swing lock (seat
rotation lock).

The OC-1A armrest with cushion is slightly inclined inwards so
that the arms are placed naturally.
Casters with big diameter and wide width reduce the resistance
and enable the operator to move easily.
Five arm shafts and a low centre of gravity hydraulic mechanism
form the stable base section.
