The Bio Active is based on the T4 model with the exception of the seat unit, the armrests follow the backrest’s movement and can be folded back. The Bio back seat is available in 3 versions:
- Seat S (Micro, 20 x 26 cm to 28 x 33.5 cm)
- Seat M (Junior, 32 x 32 cm to 41 x 38 cm)
- Seat L (Adult, 40 x 41 cm to 49 x 48 cm)
Seat width: This is adjusted by the distances between the garment protector on the left and right, as well as by the distances between the armrests. Both settings can be adjusted continuously. There are different lengths of connecting rods for armrest with special distances. If required, the rod lengths of S, M and L can be interchanged.
Seat height: The back position in the seat height can be adjusted by means of two screws.
Seat depth: For adjustment, a scale is attached to the rear side with which the seat depth can be selected.
Armrests: These can be individually adjusted in both height and armrest angle.
More detailed information can be found in the user manual.
