Features & Highlights
SiiS Therapy Chair - seat
  • The firm seat block provides the person with a maximum of sensory stimulation
  • The seat block sets the physiological body posture.
  • The sloped seat surface at the rear end of the seat block area slightly tilts the pelvis, so the spine can be straightened
  • Ergonomic seat block design
  • The longish shape of the seat helps the forward facilitation of the arms. (Stabilisation, symmetrisation, tones regulation). In addition, by bracing the arms on the set block an interim impact change for the spine can be achieved
SiiS Therapy Chair - back
  • The small, firm iliac crest support with low body contact is for stabilization
  • The iliac crest support and the impulse generators can be individually adjusted to the person in height and depth.
  • The punctiform impulse generators communicate orientation regarding the position of the back and at the same time have a stimulating effect on the body straightening and orientation process
SiiS Therapy Chair - base frame
  • The seat height adjustment is infinitely variable, allowing the legs to be positioned correctly
  • The chair is adjustable to ensure individual adaptation
  • The therapy chair is tilt resistant
  • The push bar provides good conditions for the chair to be pushed by an assistant, even over longer distances
  • The user can independently operate the lever brake and height adjustment, which provides them with a certain degree of autonomy
  • The base frame guarantees good rolling functionality and a lot of leg room which, if applicable, offers sufficient freedom of movement during the initiation of a contra lateral gait pattern (alternately setting down the feet) from a seated position
