A couple of years ago I ran a thread to try to determine why my back seat was falling apart after five years. We finally chalked it up to the idea that something got used on it that shouldn't have been. I ordered a complete new seat bottom from Donzi Direct which was drop shipped by PPI. The new seat was put in the boat in spring of 2012 so it has 2 1/2 Michigan boating seasons on it in fresh water. The boat is always stored indoors. NOTHING has been used on this new seat bottom and it is starting to fall apart like the original one did. I will never use Donzi Direct or PPI for any future upholstery work. The current damage does not show up well in the pics. Also here is a pic of the original seat after 5 or 6 years. This seat does not get abused. It is never touched during the winter. It simply gets sat on and lounged on. I've had other boats with upholstery that was used the same way and was still good after 20 years. WTF?
