not the cheapest solution and not exactly what you asked for...sometimes the best place to hide things is in plain sight.
get the largest cooler you can find...get the dimensions of the top...goto a carpentry shop or furniture re-uposterer...have something tasteful made to fit the top.
put it in front of your couch and call it a "coffee table" or put your feet on it and call it an "ottoman".
wife is happy with a new piece of "furniture" and you can store another 40 or 50 boxes.no room has been taken up in the bedroom.
