Squishy Gel Cushions let kids wiggle, improving concentration and attention skills while staying in place. They are perfect for circle time, floor time, dinnertime, homework, school work, desk work, test taking and more. Many children with autism and sensory needs can benefit from a wiggle cushion as it helps release extra energy helping make tasks that require sitting easier to complete. This gel cushion washes clean with mild soap and water making maintenance easy. The cushion does not require inflation and is 9" in diameter. The options include a fishy seat that is blue with fish inside and a bumpy option which is neon green with pvc balls inside.
