The application discloses a seat frame and a seat. The seat frame comprises a base assembly, a leg support assembly and an adjusting assembly. The base assembly comprises a fixed base and a movable base. The leg support assembly comprises a linkage component and a leg telescopic mechanism. The adjusting assembly comprises an adjusting component rotatably connected to the linkage component. The adjusting component is provided with a sliding structure and a locking structure. When the seat frame is switched between a sitting position and a TV position, the adjusting component and the movable base are slidably connected through the sliding structure, and the leg telescopic mechanism and the linkage component can be synchronously rotated. On the premise that the position of the movable base is unchanged, the leg telescopic mechanism can be independently stretched and contracted. When the seat frame is switched between a lying position and the TV position, the locking structure limits the rotation of the linkage component, thereby limiting the rotation of the leg telescopic mechanism. On the premise that the leg telescopic mechanism is kept stretched, the angle of the movable base can be independently adjusted.
