A child restraint system has a bottom portion configured to rest on a dedicated seat of a vehicle. The bottom portion has a front end, a rear end, and a pair of sides. An anchor latch system is carried by the bottom portion and has two latch belts partially housed within the bottom portion. Each latch belt has an anchor end protruding rearward from and external to the bottom portion. An adjuster is exposed on at least one side or the front end of the bottom portion. The adjuster can be manipulated to selectively retract or pay out the two latch belts simultaneously. The adjuster can have an adjustment belt protruding from one side of the bottom portion. The adjuster can have a knob positioned on the front end, one side, or both sides of the bottom portion.
