When the weather turns, these American made, marine grade covers will protect your cushions from the elements. Sunbrella’s Sur Last material is highly water resistant, as well as mold/mildew resistant. This coupled with high UV resistance and the ability to toss in the wash makes for a low maintenance, care-free solution for extending the life of your Nisswa pieces. Laying the pillows down and fastening the buckles on both ends keeps all snug, secure and clean until fairer weather returns.
