Look elsewhere. I had couch cushions re-stuffed that with what was supposed to be superior form, which I paid more for, that did not last a year before they started looking like they did before. The original form lasted eight years, so I don't know what he used. I tried to contacting him and played phone tag, my mistake by letting him know in my message why I was calling. I have moved so did not pursue by going to his shop which is in his garage.
