Sorry about the long delay on an update on this.  I emailed back an forth with Matt, sent him some fabric samples from the affected areas, and it seemed to be a one off fabric issue.  The supplier isn’t used anymore so it should 100% be a non-issue anymore.

 

I still wholeheartedly recommend the DIY’s to anyone that has decent s…[Read more]

Looking at the photos again, I tied the loops backwards from my original plan, which definitely put all the ‘pinching’ force on the tie in points as opposed to the seat back as I originally intended, and that explains the delamination perpendicular to the direction of pull– the tie down is getting…[Read more]

The the photo of the old seat is along the bottom, back right edge. It peeled back about halfway to the reinforcing strips on its own. The fraying didn’t start happening until the fabric pulled away from the TPU.

 

As for the attachment points along the side they too peel with little force.  The ones shownare just…[Read more]

I just wanted to check in with the forum here and see if anyone is having any similar issues, and if anyone has found a potential fix.  The issue only seems to present itself in areas where the non-TPU side of fabric is exposed, allowing for pretty constant wetting out of the fabric (seat, seam strips, tie downs)

For backstory,…[Read more]
