I just bought one like this. This is the first one I have found on the internet like it. This is the only table that has the "black dots" on the corners. I have an issue with the opening. I think there is a part missing on the outside edge. There is a "tab" on the outside edge it appears to need to attach to something but it has nothing to attach to on the bracket or the table. If you could send me a picture of what yours looks like from underneath, I would appreciate it VERY much.
