If you are going to use your bonsai tree as a display item in the livingroom try to choose a spot that gets a bit of light.
A good spot to use these oramamental trees is in a shelf unit or along a bookshelf. There are only a few things you need to be concerned with. First if it doesnt get any light you will need a small grow lamp to shine on it. Many bookshelves have lights in them so you would only have to replace a bulb. The other is the height of the shelf space in relation to the the size of the bonsai tree. You can always trim or prune the tree overtime to fit.
A wooden shelf unit would look the best and with the right bonsai tree would look very striking.
