Floating shelves look fragile to the naked eye because of the way they sit on the wall. All the workings of the brackets are hidden so it seems as though they are floating there on the wall. In reality they are usually much stronger than other types of shelves which are supported with traditional brackets and screws.
If you look for pre-packaged shelves and just cant seem to find any that go well in your home, you may need to take another route. This would involve doing a bit more shopping on your part but what woman does not love shopping anyway, especially when you are doing it to beautify your home. You might find that you will have to buy the shelves separately from the brackets. You may decide that you would rather go this way even if you do find that the other ones are nice.
