The mastaba of Mereruka is the largest and most elaborate of all the non-royal tombs in Saqqara with 33 rooms or chambers in total. Mereruka was the vizier to king Teti, who was the first pharaoh of the 6th dynasty Old Kingdom period of Egypt. Mereruka was married to Teti's daughter, princess Seshseshet Waatetkhethor. He was, therefore, the king's son-in-law. Princess Seshseshet Waatetkhethor is buried in Mereruka's mastaba tomb along with their son, Meriteti.
