This seating system utilizes a padded roll as the seat to help maintain proper hip abduction and prevent “scissoring” of legs caused by abnormal muscle tone. Chrome-plated steel front and rear legs adjust in height and angle to meet each child's seating requirements. Available in two sizes to fit preschoolers through adolescents. Upholstered in easy-to-clean and durable Blue Ridge vinyl, this chair includes a seat belt to provide safe restraint. Optional Lateral Supports provide additional stability when needed. Optional Adjustable Clear Acrylic Tray adjusts for height and depth and is equipped with a spill rim with easy-to-clean edges. The tray's transparent surface allows it to be used as a communication board.
