14.75 TPS coils under hips leaning

I have it enclosed with what I though was a sufficient although non-TPS provided enclosure. when I look at the part my hips are on I can see the coils are more pushed down and leaning against their quad. Do I need an even tighter enclosure, or perhaps an inch of firm foam under it to tighten it up L Anyone else seen this problem. I have also been experiencing some hip pain which is typically too soft, so I wonder if this is the related problem. Me 200lbs + side sleeper.

Off topic - but why does TPS make the coils in a lattice like this. The mini version is similar to LP coils where it is fully constrained. It seems like just another variable to fight against.

Edit : this thread from about a year ago goes into way more detail on this issue
