I always thought the rook to move like a chair.

That is one rook which can move diagonally and in non-linear motion!
Rooks are mobile towers! Tower on wheels.
The origin of chess has to be researched in its closest ancestor, the game of shatranj, from where came the words: xadrez, ajedrez, acedrez, schach, scacchi, sah, chess. In the game of Shatranj there was already an horse, apparently, even an elephant in the place of the bishop or something. The origin of shatranj is Persia and the Sasanian Empire. https://en.wikipedia.org/wiki/Shatranj
This is a great question. It's not called a rook because it's meant to represent a bird.
"In the medieval shatranj, the rook symbolized a chariot. The Persian word rukh means "chariot"(Davidson 1949:10), and the corresponding piece in the original Indian version, chaturanga, has the name ratha (meaning "chariot"). In modern times it is mostly known as हाथी (elephant) to Hindi-speaking players, while east-Asian chess games such as xiangqi and shogi have names also meaning chariot (車) for the same piece.[5]
Persian war-chariots were heavily armored, carrying a driver and at least one ranged-weapon bearer, such as an archer. The sides of the chariot were built to resemble fortified stone work, giving the impression of small, mobile buildings, causing terror on the battlefield.
In Europe the castle or tower appears for the first time in the 16th century in Vida's 1550 Ludus Scacchia, and then as a tower on the back of an elephant. In time, the elephant disappeared and only the tower was used as the piece.[6]
In the West, the rook is almost universally represented as a crenellated turret. The piece is called torre ("tower") in Italian, Portuguese, and Spanish; tour in French; toren in Dutch; Turm in German; torn in Swedish; and torni in Finnish. In Hungarian it is bástya ("bastion") and in Hebrew language it is called צריח (pronounced "Tzariach", meaning "fortified tower")."
Is a rook a person?
