Inspired by the design of old medicine balls, HOCK refined the VLUV balls by adding a comfy handle. Furthermore, we added a slim ring to the bottom panel that prevents the ball from rolling away too easily. All VLUVs are design-registered in Germany.

An important advantage of the VLUVs is that the ball cover limits the expansion of the inner ball and in return reinforces the seating feeling. The seating position is more upright. The more rounded shape allows to rotate and bob perfectly.
