Clear answers. Considered choices.

With Sit-i, free movement is created directly beneath the seat. The base remains stable, while the body is given space for natural rotations, variation, and adjustment. This encourages conscious movement while sitting.

It depends on your application. Care is the dynamic working chair for care and treatment; Care · Pro adds sensor technology. Athlete · Pro focuses on training and movement analysis, Oris on dentistry and Opus on working at a desk or at home.

The appropriate seat height and configuration depend on your height, working height and application. Include these in your quotation or advice request so we can discuss a suitable configuration with you.

That’s possible. The Sit-i offers greater freedom of movement than a traditional chair. Start gradually and alternate with your usual way of sitting. There is no one-size-fits-all approach: listen to your body and gradually increase use in a way that works for you.

Sit-i Athlete · Pro and Sit-i Care · Pro are developed with Sit-i Pro sensor technology. The current product page always states which technology and configuration belong with a model.

Sit-i Pro sensors record rotation and changes in the seat’s angle. The software displays that movement directly. Compare the measurement information with your observations and the person’s experience. The technology does not make a diagnosis.

Sit-i Pro is not a medical device. Its sensors record movement of the seat to support observation and analysis. The system does not make a diagnosis and does not replace diagnostics, clinical decision-making or the user’s professional responsibility.

Delivery times may vary depending on the model, version and current stock. The most up-to-date information is available on the product page or will be confirmed after you place your order. If you need the Sit-i by a specific date, please contact us before placing your order.

The options depend on the product and whether it was specially assembled for you. For the full terms and conditions, view the return policy or contact us before purchase if you would like confirmation.

The additional factory warranty is five years on the structure and mechanism and two years on upholstery. Pro models also have two years on electronics and sensors. Your statutory rights remain in place.
