Oh…My…God! We can’t believe we didn’t have this when we were kids! The lucky ones had a carpet that had roads and houses painted on but it never really felt right because you could just drive your little car toy all over buildings and grass.. A three dimensional carpet has a real raised boundaries that separate roads from buildings and grass. It’d a great carpet that stimulates and encourages children’s play in a creative, entertaining and interactive way with room for friends to join in! Carpets are 100% polypropylene, hypo-allergenic, anti-static, stain resistant and made from non-flammable material.
