I received a letter from Textron shortly after I bought my 2021 800SX LE saying the headrest parts were not available when the unit was manufactured, and they would notify me through the dealer when it would be available. I had to keep calling Bass Pro and finally the kit arrived. I decided to take it home and install it myself. I was pretty easy. I has three headrests attached to a single crossbar that bolts to the frame. Keep at it. The squeaky wheel gets the grease.

My 2021 800SX LE has the same problem. The bed seems to settle down when it cools down. I just ignore it. Some have tried to install a heat shield. I don't see it as a big problem.
