Sitting for a long time is unavoidable in our daily life. PG1 combines creativity and ergonomics to achieve your comfortable sitting with a rigorous attitude. PG1 is committed to making the use of the chair more suitable for the natural form of the human body, rather than the human body adapting to the chair. We hope that you can truly "Sit back and enjoy healthy life" when using the PG1 chair.
