In order to appreciate the functioning of the Z 4000 series workbench better, we have developped the Z 4007 stool. Its aluminium frame makes it robust, light and durable. In the front part, designed as a resting surface, there is a small area dedicated to storing utensils. Thanks to the pre-directional wheels the operator can move along the longitudinal axis of the coffin without modifying his/her posture. This accessory optimises the preparation phase of the coffin.
