Abstract: A seat unit for an aircraft includes an intermediate portion disposed between a first seat and a second seat. In a bed state, the intermediate portion is adjacent to a first backrest and a second backrest while a height of an upper surface of the intermediate portion substantially coincides with the height of the first backrest and the second backrest. The intermediate portion includes a vertically movable partition plate. In a state in which the partition plate is housed in the intermediate portion, the upper end of the partition plate is located at or below the height of the upper surface of the intermediate portion, and when the partition plate is raised, the upper end of the partition plate can move to a position above the eye level of a user seated on a at least a first seating portion or a second seating portion in a seat state.
