Best Child Safety Car Seat Bases Buying Guide
Before choosing the best child safety car seat base you should consider following options:
1. Installation Style: All car seats come with either an LATCH or a belt-positioning system.
LATCH stands for ‘lower anchorages and T-harness’.
This is a car seat base that uses a T-shaped clip that fits into anchor points in the car, usually found in the middle of the back seat.
Some models of LATCH base may also have a top tether which connects the back of the car seat to the top of the car. This helps to keep the car seat stable.
Belt-positioning systems are ones where you attach the car seat to the back of the driver’s or passenger’s seat using the regular seat belts.
2. Types of Car Seat Base: There are two types of car seat bases to consider:
FIXED: This is a permanent car seat base that is installed in your car. It’s great if you only have one car, or if you plan on staying in that car for a long time.
REMOVABLE: This is a portable car seat base so you can take it with you. It’s great if you share a car with others, or if you have multiple cars.
3. Where You’re Going: Your destination will also determine which type of car seat base you need. If you travel with your car seat a lot, then a removable base is best.
If you only use your car seat occasionally, a fixed car seat base is a good option. If you’re only traveling short distances, then you can get away with using the regular car’s seat belt to strap in your car seat.
4. Where You’re Staying: If you’re staying in one place for a long time, then you can get away with using your car’s standard seat belts to secure your car seat. This is great for places like RVs where people plan on staying in one place for a long time.
If you’re moving around a lot, then you’ll need a car seat base. The car seat base will allow the car seat to lock in place so it doesn’t move around while you’re driving.
5. Available Space: If you have a very small car, then you may have a hard time fitting in a regular car seat base. In that case, you can get away with using a pool noodle as a makeshift car seat base.
If you have an abundance of backseat space, then you can get away with a regular car seat base.
