I am replying as I just joined this site and your was the first post that I read..and I just posted a cake on a pedestal..too funny:) When I bought this beautiful cake stand I knew that it would only be suitable for a small cake. This stand that I used would only hold a 6 inch ( pictured) or a 8 inch cake. I have a sturdier stand that might hold a larger cake. For all two or three tier cakes I always use the heavy foam boards covered in fondant or paper with contact paper. I hope that helps.
