Invisible Table / Table / Furniture

We usually need a coffee table in our living room.
But many people can just afford a very small living room.
If they don't have guests ,
the coffee table may take a lot of space in the limited room.
Actually, a side table is enough for them in normal times.

So this "Invisible table" is designed for the limited space.
We can use it as a coffee table when we have guests in our place or as a small side table to save space.
The arc shape can enlarge useful area and be safer for children.
