Each house has at least one coffee table. They have different size and different color. But if we have a useless one after 3 or 4 months later, this furniture is going to be boring for us and still takes place in our living room.
But we have to say that some of them are very creative and useful. There are very different kinds of them, some of them have secret drawer, some of them have small chairs, some of them transform to another furniture or some of them have different geometric shape. It is your choice to find which one suits your taste.
We have a suggestion for you, buy a coffee table if you really like it, otherwise if you will never use it, it will be an area loss in your room.
