LATCH (Lower Anchors and Tethers for Children) installation system provides an alternative method for securing car seats. It uses built-in anchors and tethers in the vehicle to attach the car seat, eliminating the need to use the seat belts. LATCH installation can offer a more secure and straightforward method, and most modern vehicles are equipped with compatible anchor points. However, it is important to check the car seat and vehicle manual for specific instructions on LATCH installation.
