Crochet support/pillow

[Pashazade]

Has anyone tried the Valari gaming pillow as an arm support for crochet? The idea looks great but they are really pricey. Anyone find a good alternative?

Would a breastfeeding pillow work? It's the same shape and might be a bit cheaper.

I think these are a bit firmer than breast feeding pillows.
