We have traveled with ours up exclusively for the last 2 years and never gave it a second though. We have the two round posts with the floor sockets.
We don't lower the table into a bed, so I was thinking of trying to fasten the table to the wall so it doesn't wobble when we're all eating cereal and drinking OJ for breakfast and someone accidentally bumps the table while shuffling into the bench and all our OJs spill
When I dewinterize it next month, I'm going to look at the sockets and also come up with a solution to fasten the table to the wall.
