Lay this carpet on the floor for easy measuring, or hang it on the wall for use as a fun tool to aid children in tracking their height. Made of non-toxic and non-allergenic materials 100% polyamide means the cut pile on this play carpet is soft yet durable so it can withstand rugged wear and tear - in a classroom or at home! The gel backing keeps the rug from slipping as kids move, adding stability and safety for little ones, while double-serged edges prevent fraying.
