You probably won't want to hear/read this, but the best solution is a new seat. I installed two new custom ordered seats from shop4rvseats.com. Been very happy with the fit and finish as well as comfort. Arms are adjustable. Took 7 months to have them made/shipped but that was in the heyday of Covid.
