So Jen you are not talking about the shelf/extension that goes over the free arm - you are talking about an actual table/cabinet?
Yes, it is an actual table. The machine doesn't have the extension tray. It sits in the table that has a cutout for the free arm so that the top is level or you can fold the front and back away to use the free arm. It is one of the larger tables with four drawers down the side. I imagine it must be a Viking table for that shape of free arm to fit in? Jen
