Can I install the Billy Bookcase without wall attachment?
No, the Billy Bookcase must always be used with the wall attachment device(s) provided. The manual explicitly states that to prevent tip over, this furniture must be securely anchored to the wall. Installing it without wall attachment creates a serious safety hazard.
