Seat height adjustment
The seat unit can be lowered down to the ground. Apply the right foot pedal at the back of
the base frame (fig. 3-4). Now push the seat unit down (at the back, the armrests or the push
bar, if available) or pull it upwards until the desired height is reached. To keep the height,
simply remove your foot from the pedal. The seat height can also be adjusted during use of
the chair. It may then be necessary for two people to lift the seat to the desired height. For
safety reasons the seat height adjustment can be locked. The adjustment is locked when the
locking pin to the left of the pedal is engaged (fig. 4). To unlock, pull out the locking pin and
do a quarter turn.
Seat tilt-in-space adjustment
To adjust the seat tilt-in-space, use the pedal on the left side of the rear frame (fig. 5). First,
engage the brakes. Now either push the seat unit forwards (at the back, the armrests or the
push bar, if available) or pull it backwards until the desired angle is reached. To keep the
angle, remove your foot from the pedal. The seat tilt-in-space can also be adjusted during
use of the chair. It may then be necessary for two people to adjust the desired seat angle. For
safety reasons the seat tilt-in-space adjustment can be locked. The adjustment is locked when
the locking pin to the left of the pedal is engaged (fig. 4-5). To unlock, pull out the locking
pin and do a quarter turn.
IMPORTANT: The seat height adjustment and seat tilt-in-space adjustment should always be locked during
use of the chair.
CAUTION: When adjusting the seat height or seat tilt-in-space one person must secure the seating systems with both
hands to avoid sudden changes of the child’s position. We recommend carrying out this setting without
the child in the seat unit.
Seat cushion
The seat cushion can individually be adjusted to the special needs of the children. Open the zipper at the cushion and
place the foam parts as desired. (fig. 6)
Seat width
Loosen the hip seat guide screws from above using an Allen key and shift the hip guides accordingly. (fig. 7)
Seat depth
Loosen the Allen screws (also for the adjustment of the seat width) on the seating surface and pull out the seat plate.
(fig. 7)
Tip: For easy adjustment of the seat depth, grip the front edge of the seat with one hand and press against bottom
part of the backrest (concentric) with the other hand.
The depth of the hip guides can be adjusted, as well. Loosen the two screws, adjust the desired depth, and retighten the
screws. (fig. 8)
Back height
Loosen both knurled nuts at the back of the seat unit and adjust the desired height. (fig. 9)
Note: The upper spring element should be removed for low back heights in order to facilitate an ergonomically correct
sitting posture. (s. spring element)
Headrest
The height and angle of the headrest may be adjusted individually by loosening both wing nuts on the headrest.
(fig. 10)
Backrest adjustment by gas spring
The release button at the top of the backrest has a safety lock. To unlock, slightly lift the release button and let it click
into place again after a quarter turn. Now, you can adjust the back angle. Hold the backrest with one hand and press
the release button down with the other hand. Adjust desired position by pushing or lifting the backrest. Then release the
button again. The seat unit automatically slides forwards on its rails, shifting the centre of gravity. (fig. 11) Make sure to
relock the release button after each adjustment. (fig. 11)
