I don't know why but for some reason these covers seem to dry out and a chalky residue appears on them. I was unaware that they were covered by warranty so I am on my third one as the first one I replaced and spent the listed price. The last one tore across the top and I was forced to put a tarp over it. I'm hoping that this replacement will last because as a result of the splitting of the fabric, my loveseat cushions were left damaged. I really wish they would bring back the green color or offer more decorative colors. Hopefully some improvement will be made by the manufacturer so these covers will last for more than a year.
