Features and Functions
Seat cushions
The stools are available either with a round or ergonomically shaped, or as a saddles style seat cushion.
Height adjustment
The stools are height adjustable. The adjustment for the pneumatic gas spring on the ak 445 and ak 447 models is either hand- or heel kick operated. The hydraulic pump on the ak 446 is foot operated
Back rest
The back rests are vertically adjustable.
The back rest can be locked at any desired angle within the movement limitations. If the locking mechanism is unlocked, the spring loaded back rest will follow the movements of the upper body and apply a soft, comfortable pressure to the lumbar spine.
Arm rests
The various arm rests have been designed to support the specific needs in many medical specialties. The pivoting and ball joint articulates can be set up to support the procedure and, at the same time, guarantee a comfortable and fatigue free seating to the physician.
The extended arm rest shaft is very popular in neuro (skull) surgery or endoscopic ENT examinations.
