The key to IKEA furniture, I have found, is to place it where you want it and never move it. I have Billy bookcases that have lasted 15 years while being FULLY loaded. I also have had to replace my son's Billy cases as we've rearranged and updated his bedroom multiple times over the years. He doesn't abuse them, they just don't like be moved in and out the room,even empty, for painting or other projects.
