I am downsizing and am attempting to dismantle an Ikea desk. There is a shelving unit attached above the desk (part of orginal design) and it looks as if it ought to come off somehow. But we have tried unscrewing things and the screws just get a bit looser and the top doesn't seem ready to come off.
My Ex assembled it, and neither me or helpful friend know how it's put together in the first place. So we are working from a position of ignorance! Have looked on net and found a reference to difficult "round the corner" fixings - maybe this is what we're up against?
Sometimes their screws are a type which slot in and turn thru 90 or 180 degrees to tighten the sections together. If they loosen then maybe you'll find that they come apart when loose, IYSWIM. Loosen all the screws down one side and see if that section pulls apart.
