SIT 4 Configurator

The ENT treatment chair

Form and function

The examination and treatment chair SIT 4 combines slim clean design with full functionality and ergonomics: a result of elaborated design and 15 years of continuous development. With its sophisticated features, it presents itself as a stylish full-function chair.

High quality

The use of high quality materials, precise workmanship and strengthening particularly exposed seat-parts ensure the durability of the SIT 4 even under heavy use in clinics and medical practices.

Optionally all functions are electric motor operated, on request by remote control.

Optimal treatment

A special feature of the SIT 4 is the sloping telescopic column, as a result of which the patient is automatically brought towards the doctor when the chair is raised. This ensures even better access to the patient.

The version with 30 cm lifting range ensures to use the chair for adults as well as for children without special seats. The height of the treatment chair is easily adjusted using the footswitches built into both sides of the base plate. There is also the option of an external footswitch.

Optional: 30 cm telescopic column

Comfortable sitting and reclining

While the backrest of the SIT 4 PLUS is adjusted, the armrests and leg rest simultaneously follow the chair's sequence of movement until it reaches a completely horizontal position thus ensuring perfect support and patient comfort. In case of a collapsing patient the backrest can quickly be brought into the -10° Trendelenburg position. A floor fixing is not necessary.

The SIT 4 pendulum chair allows it to perform different pendulum methods. These are controlled by a remote control. The program-controlled electric motor performs various pendulum tests (5-90 sec) and has a freely programmable interface.

Backrest in -10° pretilt

Synchronous motion

-10° Trendelenburg position


The SIT 4 is smoothly rotatable by 360°, equipped with a 90° detent and a  locking brake. So each position is fast and precisely adjustable. As an option, the rotation can be operated by an electric motor (by foot pedal or remote control) up to 180° left or right.

The version with a rotatable seat with 90° locating mechanism facilitates rapid changes of the patient's position with better access to the patient's ear.

Because of the synchronous movement of arm rests and leg rests during adjustment of the backrest, the patient is continuously in a pleasant and comfortable position. If necessary it is possible to raise the simultaneously following footrest separately, to ensure secure contact of the calves with the chair.
