Stepping into one of these whole body blankets is like nothing you have ever done before! You just need to stretch, push and move around as you explore the space around you. The stretchy pushback quality of the fabric provides a whole-bodies-worth of proprioceptive feedback. This helps calm the central nervous system and teaches the child or adult about where their body is in space. Made of 4 way stretch lycra with velcro closure. For the more cautious experience seekers, head/face can remain outside the blanket. 3 sizes available.
