Tumble Forms 2 Universal Side Lyer minimizes the time therapist, teacher or aide needs to monitor the positioning of neurologically impaired children. Universal size accommodates preschool through adolescent children. The 42"L x 23"W base is angled upward so gravity helps position the child. Two soft, easy-to-use straps permit infinite adjustment. Seamless, soft upholstery is urine- proof and easy to clean. Two block modules (3" x 5" x 11") can be used as a headrest or for leg abduction (not included). Universal Side Lyer is 14"D. Backrest is 9"H. Latex free.
