I'm trying to figure out what sort of cake stand to use for the wedding cake I'll be making. It will be three tiers and each tiers will have 2 round cakes (bottom is 10", middle is 8", and top is 6") so it will be fairly heavy once the buttercream, fondant, and details are all added. I've never made one like this before so I'm not sure where to even look for the proper stand. I don't want something that will weaken and crumble mid-reception!

how about using a silver plateau riser instead of a pedestal cake stand? They are great for cakes with added weight if you really must use one at all.
I bought mine without those tiny legs on it, as I wasn't sure about them indenting wooden tables if the cake was REALLY heavy. It's fantastically sturdy, that's for certain.

Oh that's a great idea. Thanks antonia!

Check out milkglass cake stands--they are a lot stronger than ceramic ones (although I've had sucess with 4 tiers of real cake in ceramic).
