shifts back and forth as the cylinder rolls beneath it. In almost all models the two flat ends of the wheel/roller are about as far from each other as the width of the board. In most models the axis of the roller is perpendicular to the board's length. Thus, as the rider's weight moves over the roller, the board both tilts from side to side and also slides sideways. In models whose roller can be placed with its axis parallel to the board's length, the board slides and tilts toward the front and back (if the rider's feet are oriented accordingly).

The holes in it allow water to fill it, making it neutrally buoyant (i.e., neither sinking on its own nor floating up to the water's surface) so that it is easier to control and safer than it would be if this wobble board were more buoyant. Two products that Theraquatics Australia calls balance boards, its Star Balance Board and its Theraquatics Balance Board with Straps, are not balance boards in the familiar sense of the term, though they can be used for practicing balance skills.

Feeling like falling can raise fears and provoke reflexes that while useful on a stable surface can be counter-productive on a balance board, such as throwing the arms forward to catch the fall or over-correcting and sharply shifting weight onto the opposite leg, causing a fall in the opposite direction.

Risk can be lowered by anticipating falls and clearing the surrounding area of objects that the rider might fall onto, and making sure that the surface is soft. Some of the best surfaces for balance boarding include a soft yoga mat, a patch of grass, or the sand.
