Stapelstein® BoardA complementary product to the Original, the Board is a multi use element and it is ideal for active balance exercises and dynamic sitting. The Board can serve as a sturdy base to a large stack of elements, or turn your stack upside down to create a topsy turvy balance chair where the seat height can be adjusted individually and easily. On its own, toss like a disk, spin like a top, and of course, try to keep your balance for wiggly fun indoors or out.
