Curious how long the seat foam should provide proper support. I have an Oregon Aero seat cushion, purchased in Oct. 2016, in my RV-8. It was super comfortable when new, but has been slowly collapsing, I now have to put about 1 1/2 inch thick (styrofoam) spacer under the cushion to get the same seat height as when the seat foam was new. Plus it is not near as comfortable as when new. Seems like it should last more than 4 years and about 350 flight hours. What have most folks experienced with your seats.
