Manufactured using 100-percent two-ply texturized polypropylene yarns makes this rug a true indoor and outdoor rug. Fade-resistant and durable, these reversible rugs will stand up to all the demands of family life. Rhody Rug fills its braids with non-absorbent synthetic fiber, woven into thick tubes to create a durable soft cushion that will not crush. This non-absorbent material allows the air to flow through the rug so that it dries quickly and resists mildew.
