I think it was posted here, but I know it made its rounds on Facebook - that blog post by the mother who lost her daughter after a dresser fell on her. :-(
We set out to anchor all of our furniture after that and bought steel cable kits by Quakehold for about $6 each (with shipping) on Amazon. Just a quick PSA that they installed really easily and this furniture is going absolutely nowhere. The plastic kits made by kid safety gear companies made me nervous - especially with our big 6 foot book cases. These are seriously rock solid.
So, if you're looking for anchor kits, I highly recommend these!
