I returned this lounge cushion because it was slippery when you stretched out on it. My Lounge is iron, I found myself sliding off which is amusing for a few minutes. I had others for years that were a heavy treated cotton duck and 4 thick but I could not find that quality again for less than $300 ea. These look great and I am sure they are waterproof, but I would not leave them or any cushion outside when not in use .
Nice and look great
