These cushions are so comfortable.  We had a very heavy rainstorm late evening and I was concerned whether to leave my chairs out or bring them in.  I decided to leave them out as a test of their resilistence to the rain.  Boy, was I surprised the next morning when they were dry.  My next door neighbor has Sunbrella cushions as well and theirs were still wet.  
My only disappointment was the color Brass I had chosen.  I wish yhe limited selection of colors had beige but I was very happy with the quality of these cushions.
