The Wiggle Cushion is a perfect solution for children who have a tough time sitting still. The Wiggle Cushion is a cross between a ball chair and a seat cushion. You can inflate the Wiggle Cushion to the max to stimulate balance and core work, or deflate to use as a seat cushion which encourages movement. One side of the cushion is a smooth surface, the other side has slightly raised "bumps." You can choose between receiving tactile input or sitting on a smooth surface. It provides balance therapy and tactile input, which is great for kids with sensory processing and focus challenges to improve focusDetails:Available in multiple colors12" diameter, 4.25" heightCushion can be blown up to 3.5" high (for a less stable, firm, rounded cushion) by straw (not included), mouth or hand pumpIncludes free hand pump and ideas for useGreat alternative to a ball chair that can be used in school, home, clinic or travelA subtle fidget reduces distraction, fights boredom, and helps kids be ready to learnMade from PVC, latex-freeGreat for kids with sensory processing and focus challenges to improve focusFor ages 3 through teen
