I redid the forward portion of the seat with new foam and fiberglass due to large areas that were delaminated. After fixing that, I removed and replaced the bottom two layers of glass for the same reason. After making the repairs, I made four ribs and microed them to the bottom of the seat. After it cured, I added fiberglass tape to the joints and installed the seat in the plane. I am able to step on the seat at any spot without issue and it holds my weight while sitting. I will load test the seat with two people and ensure it can handle additional G's to make sure.
