“I’m not sure that “bosis” is such a problem because I think you can just make sure that there is a bentcher on the table or that it is set before candle-lighting (making sure that there is at least one non-disposable item).”
You can put a bentcher (or a challah as some have the minhag), but if you always put the candles on the table sooner or later you will forget and that will be the week that you want to move the table.
