What's the knack for removing a front head restraint? Pressing the button allows height adjustment but doesn't allow removal and I'm loath to use too much force.

Had to do this only last week to load some skirting boards!

There's a second button on the second support, but it doesn't protrude so you'll need to press it with a fingernail or screwdriver or similar. It's a bit fiddly, but they do come off.

Brilliant - a stealth button! Thanks for that.
