I'm using my phone, Gordon, and have just edited my post re the Burstner Drop Down bed after about 30-45 minutes.
At the bottom of the Post, about opposite the last line of the Post, there is a small box, marked 'More'. If you click on that button, it opens a drop down menu and 'Edit' is the first item, and after making your changes, the 'Save' and 'Cancel' buttons for the Changes appear
