The handle does not extend what should I do?

The Doona handle is designed to prevent misuse, therefore it can be extended only when the handle is in rear facing stroller position.

To rotate the handle into a stroller mode, press both white buttons simultaneously (located on both sides of the handles) and then rotate the handle to rear facing stroller position.

To extend the handle press the white button at the top of the handle and then pull the handle towards you.
