The heaviest plates will NOT tip over, they stay secure and upright in the slots for plates.  The rack has a utensil holder that snaps onto any part of the outer rubber rim you want it located and it will NOT fall over no matter how much silverware is in it.  I LOVE this!  I also give a quick wipe down after it's empty to avoid any possible rusting.  I bought  the mini one as well.. see photo.
