A stool with very similar shaped legs to this, from Beni Hasan, is known from the Ashmolean Museum (Ashmolean E4162; Killen 1994, fig. 46).
It is noticeable that all the stool legs from ancient Egypt suggest a very low stool height. Although the ancient Egyptians would have been shorter than us, the stools are still very low. It is not known if this was to conserve wood or because a lower stool height was preferred for other reasons.
