TheraPro's Disc Cushion by AeroMat

Another great air cushion! Air-filled, made of soft, pliable PVC and a great size (13-1/2"). Soft spikes on the bottom and slightly raised "pebbles" on the top offer a variety of surface textures. Sitting on this disc cushion has the feel of a therapy ball, promoting attention and improving balance and strengthening back muscles. Also use for working on standing balance.
