From the Zhang family kilns
Ceramic pillows were among the common products of the Cizhou kilns, and when moulds were used it was mainly for them. Unusually for Chinese pottery, many carry a stamp or an inscription: a large group, mostly of the 12th and 13th centuries, is stamped with the name of the Zhang family workshop in Henan, and at least one tiger-shaped headrest carries that stamp. Other kilns made moulded shapes with a flat panel for the head, and tigers are common among them.
To verify: A dated tiger pillow: the Brooklyn Museum lists one with an inscription giving a date that probably corresponds to 1182 and a price of 31 copper coins, but we could not open its page to check
