These wobble cushions are designed to be filled with air. This creates a moving surface for the child to sit on. The idea is that this movement (vestibular input) will help keep the cild more alert. 
 
The aim of the wobble cushion is to help the child (or adult) with attention and focus.
 
This is great for  the classroom if you have a child that struggles to sit still. Children can wriggle around using that excess energy quietly.
 
 Our wobble cusion is textured on one side. Another great tactile experience helping with focus, balance and muscle strength.
 
Comes with its own pump.
