Front seat loose

I think my front seat is starting to succumb to my fat ass. I feel it shifting slightly when I break and accelerate. Anyone experience this? It is a 23 Limited with full power seats. Does not seem to be loose bolts. I am out of warranty, so this one is on me to figure out.

 

I had that problem with mine, and the dealership service dept was never able to resolve it. They said the re-tightened some bolts, but still had the same problem. With the amount of problems the truck had, I traded it in for something else, so not sure if the new owner had anything done about it.
