Furniture Design FlexSit Stool by Xiying Bao FlexSit, born to be “unstable ”, is not only a rocking stool with a range of options included but also a fun and ergonomic seating solution for the home or office. In consideration of practicability and sitting experience, the design of a spherical bottom was applied to the stool in order to provide a extremely different but interesting way of “unstable” sitting. Moreover, the method of modularity offers customers the possibility of personal customization. The vibrant color matching also perfectly meets the needs of young user generations.
