Welcome this beautiful, sustainably forested teak mat for its eco-friendliness, and weather resistance. Consider its raised, slatted design diverts moisture and debris. Definitely not slippery when wet. Teak wood is prized for its beauty and functionality as well as its durability. All-natural teak wood, harvested in Indonesian teak farms, is naturally weather and waterproof due to the abundance of natural oils. These same oils protect the wood from mold, mildew, and termite infestation. All of these features make teak wood the ideal material for spas, baths, poolside, and for patio furniture. Natural finish requires cleaning and sealing twice per year.
