The table is like a solid cube. Until it opens It has a flat service when it is closed or not, which is a characteristic of a table. Either way it is a table. it could be a side table when it looks like a cube or dinner for two when you pull it apart.
Store blankets or .Possibly add storage to sofa table behind couch. Instead of lid opening up to hit the wall, I would have it up up from left to right or have a centerfold where it opens left/right & right/left at the same time
