Colorful uppercase letters surround the perimeter of this brightly colored educational rug. The vibrant alphabet aids in color and letter identification, and the center rectangle provides plenty of space for reading and learning. The 3-ply felt backing increases sound and thermal insulation, and also prevents wrinkling and creasing. Made of non-toxic and non-allergenic materials, 100% polyamide means it is able to withstand rugged wear and tear - in a classroom or at home! All Learning Carpets items meet CAL TB117-13 flammability standards. This great carpet has a limited lifetime warranty and is available in a smartly priced "value" size rectangle of 51"L x 79"W.
