Note how the reversible base creates two benches. When the bench is straddled, as a bolster bench, the flat surface of the Adjustable Straddle Bench blocks the knees from rolling inward. The controlled rocking on the base encourages lateral weight shifting, righting, and balance responses. The height adjustability of the side rockers allows one end of the bench to be raised for pelvic positioning. Used as a forward rocker, the bench encourages weight shifting, righting, and balance responses in an anterior/posterior direction. It is also very helpful in sit to stand activities.
