I have at home a couple of acrylic pieces cut to size which I use as plates (double cardboard has worked as well) and then divide them using a 4-inch wide PVC pipe. It works pretty nicely and it is very stable. Once you put them in place they are not going anywhere but, if you don't feel safe, you can use some double sided or mounting tape to secure them in place.
You can wrap the PVC in color gift paper or in any other type of paper you like to go with your cake. I don't have pictures here with me 'cause I'm at work right now but here is the idea.
