Child seat

A child seat includes a seat shell, a retractor assembly including a movable member connected with the seat shell, an anchor strap portion and an adjustment strap respectively connected with the movable member, and a lock assembled with the seat shell. The anchor strap portion extends outward from the seat shell, and is provided with a fastener operable to attach with an anchor structure of a vehicle. The adjustment strap has a first end portion connected with the movable member and a second end portion extending outside the seat shell, and extends through the lock at a location between the first and second end portions. The movable member is movable in a first direction to pull the anchor strap portion for reducing a length thereof outside the seat shell, and in an opposite second direction to pull the adjustment strap for reducing a length thereof outside the seat shell.
