Chairs are much too simple – or simply too much

 

Human anatomy isn't designed for sitting on firm chairs or soft, low pieces of furniture – especially not for any length of time.

 

A static sitting posture causes discomfort and restlessness because the blood flow between the body and legs is restricted.

 

A sloping seat allows blood to flow more freely. A correct rocking movement can also be stimulating and relaxing while improving concentration.

​

Many ergonomic solutions give relatively pronounced slope movements and are only suitable for large office and easy chairs. Investigations in the 1990s showed that the stimulating ergonomic effects are achieved with even small seat motions – large movements are not really necessary.

 

The many adjustment possibilities offered by office chairs are seldom utilised by users – or are used wrongly.
