Ordered headrests for the front seat and thought I was getting ultimate but came as premium. No faux leather cover just black plastic. Ultimate not available from Polaris and premium back ordered. Looked at the headrest there is a plastic " J " hook that once it slides in place there seems no way to release them. Luckily I did not insert in the fronts seats or they would be there for eternity. If anybody wants the premium headrest will sell for 100 bucks they are 129.00 on the Polaris website. You benefit from my failure to read the fine print close enough.
