Swiss Viva Grand SM

Compact mobility meets healthy standing

The perfect combenation

Standing meets agile and compact – the Grand SM is the perfect combination of standing function and mid-wheel drive. What does that mean? You can go virtually anywhere. And once you’re there, you simply achieve more standing at eye level, whether you’re in a stadium, at the beach or at the supermarket. Its origin is also unique: it comes from feedback from you, our users.

How it can change your life

Go everywhere…

Narrow width, mid-wheel drive and independent suspension make the SM agile and suitable for any terrain – indoors and out. The bottom line is that narrow spaces, inclines and difficult terrain don’t stop you in your tracks. You can move effortlessly around a stadium, on woodland paths and beaches, at the supermarket checkout and in your kitchen. Or ride right up to the table – thanks to one of the lowest seat heights on the market.

…and achieve more while standing

Once you’ve arrived, the standing function brings you easily and painlessly (i.e. with technical precision) into a standing position. And you’re ready. For a clear view over a railing or to the stage. For face-to-face conversations at the centre of the action. For reaching up to the kitchen shelf or for the glass on the bar. For a little more independence and autonomy in everyday life.

Stand up for your health

The SM allows you to move into an almost perfect standing position, which can slow the progress of an underlying illness and reduce accompanying symptoms, for example through improved oxy-gen circulation, increased bone density, maintaining joint mobility and digestive function all the way to decubitus prophylaxis. In other words: standing is simply good for you.

Born of user feedback

We say THANK YOU! Because the initiative for the SM came from you, our users! The combina-tion of standing function and mid-wheel drive comes straight from real life, as a popular result of our customising process.

At the start of every Swiss Viva we ask: Where are you travelling? What are you planning to do? We listen, ask questions and contribute our expertise. In combination with the immense possibili-ties of our customisation process, we then create exactly the chair that best suits your everyday life. And sometimes even a new model.
