I11s seat not staying in tracks.

I recently purchased a used i11s and my vantage seat slips out of the front tracks when I lean back on the seat. I tightened the straps as tight as possible on all sides. Is there any fix for this issue? The front and back tracks don’t seem to have any warping or damage either.

Hi, I have had an i11s for 8 years and struggled with the same issue. I replaced all 4 of the seat straps with these https://www.amazon.com/dp/B0DYSDJK6M?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 Once you find the correct length for the cords you will need to trim them and then I used a heat gun to seal the ends. Tighten them before you sit down and once you sit down pull the cords one more "click" tight. Problem solved for me.
