This stimulating "aquarium" activity therapy pad is gel-filled and houses four colorful fish to push and manipulate. Manipulating the mat addresses finger isolation and strength. It also serves as a fine-motor tool for eye-hand coordination. It can also be effective in reducing anxiety and boredom. Place the pad on a convenient surface or lap, and although it can be challenging, the user should be encouraged to move the four fish around the aquarium pad. Can be warmed in warm water or cooled in a refrigerator for an extra sensory experience. Pad is 4 pounds for additional weighted therapy use. Cleans easily with soap and water or disinfectant cloths. Measures 19"L x 12"W.
