Info: Set of Four 5 cm (2-inch) High Extensions to Insert the Ball Chair Wheels Into

These extensions are for use with the original Aviva Ball Chair we formerly sold here at Aviva (one is pictured on our other Ball Chair Accessories page), and will also fit the similarly shaped BalanceBall Chair from Gaiam.

bag of 4 ball chair leg height extenders

These ball chair leg height extenders are recommended for taller users, or for those using a ball chair to sit at a slightly higher desk or table or counter surface. (So while the top of a well-inflated ball on a standard chair might be about 23 inches from the ground while on the wheels alone, it would sit 25 inches high with these extenders in place.)

They come in a set of four, and have the right inserts on top to fit into the frame of the chair (including a metal one which swivels) and the right opening on the bottom to snap the ball chair casters into.
