The unique design of the Theranoodle makes it a great all round floatation device. It can be used to maintain an upright, supine or prone position in the water. The mesh platform can also be sat on or used as a head support. As a water confidence tool, the Theranoodle can help those new to water to stay in the proper position, exercising the appropriate muscles and moving forward. Finally, the Theranoodle can simply provide underarm support during aquatic rehabilitation.This size is appropriate for children.
