Modular customisation
The Swiss Viva Grand F is built on a modular concept with a wide range of factory and special-build options (different lift types, chassis variants, cushion and upholstery options) so the chair can be configured to the user’s clinical and daily requirements.

Compactness and seating geometry
Designed to provide a low seat height and narrow overall width while allowing a wide range of seat widths and depths. This facilitates transfers, sitting at tables and passing through doors.

Indoor and outdoor mobility
Dual 400 W drive motors and independent wheel suspension enable use on demanding outdoor terrain while compact footprint and modern controls support indoor mobility and manoeuvring.

Durability and serviceability
Construction allows for component replacement and retrofit options to support long-term use and modifications as clinical needs evolve.
