Improvements for child restraint systems are directed specifically to the covers, handles, and harnesses thereof. A child restraint cover is readily removed without having to detach the harness from the seat. A soft and semi rigid child restraint handle includes members that are tied together in a crossover fashion. Another handle of the invention spans above the restraint in a head to foot direction. A further handle design includes dual integrated handles. 5-point and 7-point harnesses that do not require threading a child's limbs through harness loops are also provided. A harness height adjuster is also described.
