What size and type of screws do you use on Melamine wood?

Nope. You've got to secure it from side to side so it won't tilt and collapse.

Run one piece across the top or bottom, from side to side.

i don't see how that would stop it from tilting.

i'm thinking of getting that ultra thin wood (not too sure whats its called) that is used behind dressers as the back then nail it in??
