Provided are an ottoman linkage device, a frame body, and a seat. The ottoman linkage device includes an upper link, a lower link, a middle ottoman link, a first front ottoman link, a second front ottoman link, a first connection link, a second connection link, a front ottoman bracket, and a middle ottoman bracket. The upper link or the lower link is rotatable under a driving force to make the ottoman linkage device unfold or fold. By changing the length of the first connection link and the length of the second connection link, the magnitude of the driving force of the first connection link can be adjusted.
