A child booster seat includes a seat shell, and armrests that can be conveniently placed in an outer envelop of the seat shell. The armrests can be placed in a storage cavity of the seat shell, and deployed outside the storage cavity for use. When the armrests are received in the seat shell, the outer envelop of the booster seat can substantially match with the outer contour shape of the seat shell. The booster seat can thereby occupy a smaller volume.
