stuffed zafu

I bought a buckwheat-hull-stuffed zafu. I thought it would be great compared to the sofa cushion I had been sitting on. It 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 stiffer, and 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.
