Allow children to become engineers of their own city! Little ones can drive toy trucks and cars on the carpet road and construct house and businesses on the open surfaces. This educational rug will spark their creative imagination! Made of non-toxic and non-allergenic materials 100% polyamide means the cut pile on this 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. All Learning Carpets have a limited liferime warranty and meet Class I flammability and CAL TB-117-13 Flammability standards.
