Foam blocks for hull support during storage

There are lots of photos of cats on foam blocks on the net. They appear to be about 18 inches per side , cut to confirm to hull shape. I was unable to locate them online. Are these purchased or home made? If so, where do you get the foam? Big blocks of closed cell foam are pricey through McMaster. I don't want to guess on the density at those prices. Thanks.
