Thicker than what I'd thought it would be.  Nice surprise.  I was looking for a blue and white stripe to match the other cushions that I already had.  The picture did not provide a close up and I imagined that it was a solid blue stripe like my other cushions.  It turned out to be more like a denim material and the blue was not as dark as in the picture, which was disappointing.  I decided to keep the cushions because the 2 lounge chairs are located some distance away from the other chairs that it wouldn't matter too much.
