How do you remove the rear seat headrest on a 2004 gmc envoy?

To remove the rear seat headrest on a 2004 GMC Envoy, locate the release buttons or levers on the sides of the headrest posts. Press or pull these buttons while gently pulling the headrest upward. If there are no visible buttons, check for a small release tab that may need to be pressed to allow the headrest to be lifted out. Once released, the headrest should come out easily.
