I purchased these pillows for the wrought iron chairs on my front porch.  My son loves these pillows.  He said they are so thick, we are going to have to take them in when it rain.  I said no, they are suppose to be water repellent.  H pored water on these and the water beaded up and rolled off. He said they are water repellent. There was a tornado in Chicago on August 10.  after the heavy rain, I went outside to look at the pillows,  there was standing water on the pillows, I lifted the pillows so the water could run off.  The water ran off the pillows.  The   water did not soak in to the pillows.  I was sitting on the pillows the next morning.  if not for the tree branches all over my lawn, I would have not known that it rained.
