Abstract
Disclosed are a child seat frame and a compact collapsible stroller. The child seat frame includes a seat mounting part, a lower frame body, and an upper frame body. The upper frame body is provided with an upper frame body lock which can be actuated to lock and disengage from a second latch part, and the upper frame body is pivotable relative to a lower seat frame hub when the upper frame body lock is disengaged from the lower seat frame hub; and when the lower frame body pivots relative to the seat mounting part, the upper frame body lock locks over the second latch part. The child seat frame can be folded in a main suitable for the folding boundary dimensions of a main stroller frame, thereby maintaining the folding dimensions of a stroller unit to a minimum.
