The philosophy is clear in RH Logic through its unique “two-point principle” 2PP™, which ensures that your body gets the variety and support it needs to move. Adjust the seat depth, angle and height so that the chair is tailored to your body shape for maximum support, relief and promoted blood circulation. The sloping shape of the seat reduces pressure on the lower thigh and thus also increases circulation in the legs.
Sitting upright while moving allows you to breathe better and provide your body with oxygen. Tools such as the “Tvedts” pillow push your shoulder blades back, which opens up your chest for better breathing. This in turn increases concentration and performance.
RH Logic has been tested by Swedish researchers and the results of the study also showed that after a short period of time a positive impact on performance could be seen. The chair supports you in all working positions, helps you sit correctly and breathe properly.
