I recently purchased an 85300td. When I got it, the mbtex covering on the rear seat bases (split seats) was loose from the frame in the bottom on the back. This is visible when the bases are flipped forward to utilize the back area and obvious even when flipped down since the MBtex looks loose on the seat.
I removed the bases, turned them upside down, compressed the seat, then fit the MBtex back down into the lip on the base. It did not seem to have any other means of securing it other than the tension of making the 180 degree turn around that lip.
How, a month later, it has come loose again. Should I be doing something else to secure that MBtex under that lip?
