The Classroom Positioner Desk/Standeris a dynamic addition to the Classroom Positioner Chair.  It provides the seated child with an angle and height adjustable desk surface.  Additionally, the desk can be raised and moved away to allow the child to come to a supporting standing position.  The child can experiment with the sit to stand movement or be encouraged to remain standing.  The optional Posterior Pelvic Support may be used to help maintain the standing position.
