I had bought a buckwheat hull stuffed zafu. Thought it was great compared to the sofa cushion I was sitting on. Turns out it was not so great. Too short. Too conforming. In half lotus my left thigh bore down on my right foot and cut off circulation. I stuffed the zafu this last weekend with some synthetic doll-stuffing (in addition to the hull already in it). It is much better now.
I think, at a minimum, a zafu should be at least as thick as your thigh when you are sitting on it.
