Many times when you buy furniture, you will get brackets along with it that many will just throw out. What are they for? Their purpose is to prevent furniture tip-overs.
You might think that the furniture in your home is pretty stable, but this is not always the case. While your dresser might not tip over from having one drawer pulled open, you could try opening a second one and see how it feels. If you were to add the weight of a child trying to climb up, you could easily see the danger. In fact, many children are hurt by falling furniture every year.
Installing an anti-tipping bracket is not very complicated, however, it is important that it is done correctly or it will do no good. The ideal spot to install them is directly into a stud for maximum support. If this is not possible, you should use an anchor that is sturdy enough to handle the weight of the furniture, as well as, anything that might be loading it down.
