ak447 – the saddle stool
The ak447 doctor’s stool is equipped with a saddle seat and can be ordered with or without adjustable armrests and backrest. The sturdy castor cross holds five high-quality castors and provides the necessary mobility. The height can be adjusted using a gas pressure spring, which can be ordered with a foot or hand release. Comfortable and flexible armrests can be easily adjusted to the desired position. The armrests can be easily navigated with the aid of horizontally movable armrest holders. The ak445 doctor’s stool can optionally be fitted with pre-shaped multi-directional multi-joint armrests. This allows even finer adjustment of the forearm/hand support during an operation. To set a comfortable sitting position, the seat of the ak447 saddle stool can be tilted forwards or backwards by approx. 10 degrees. The AKRUS upholstery in handcrafted quality in combination with a wide range of colors allows for color matching to the clinic or practice environment. The ak447 saddle stool is delivered fully assembled and the use of high-quality components ensures many years of reliable use when used as intended. Authorized medical technology dealers are available for service requests.
