This unique product is the standard "wobble cushion" with the addition of an attractive, zippered, overlay that can be removed and washed. Sitting on a balance disc provides similar benefits to those of sitting on stability or a swiss ball. It is used by many in place of a ball in an office or other environments where it may not be feasible to bring in a ball. The disc can also be used as a textured seat cushion for children that have trouble sitting still. The disc allows them to wiggle and moves around while staying seated. The overlay makes sitting on the disc more comfortable and helps avoid the stickiness sometimes associated with sitting on discs, and balls. The overlay also features a handle so that the disc can be easily transferred from seat to seat.
