Final Prototype
The F-Drive’s unique, dynamic design and minimal number of parts allow the user to mount the drive onto the chair frame without the need for fixings or tools. Thanks to its compact design, the F-Drive fits easily under any chair.
Operation principles
Upright Sitting Position
The F-Drive is attached to two of the chair’s struts without the need for tools – using a clip fastener on the round tube and a sliding mechanism on the square tube. Once the power supply and hand control have been connected, the chair is ready for immediate use.
Backed up position
At the touch of a button, the armchair can be gently moved into the desired reclining position – and back into the sitting position again. The movement can be stopped at any time once the desired angle has been reached.

The TriaLily
Perfection in design and ergonomics
The TriaLily has been specially designed for the F-Drive. Thanks to its ergonomic shape, it fits comfortably in the hand. The top button moves the chair into the sitting position, whilst the bottom button moves it into the reclining position. The optional gooseneck mount ensures that the chair can still be operated comfortably whilst reclining.
