Infant Car Seats With Rigid Lower Anchors: Are They Safer? Expert Guide

‍Choosing the right infant car seat can be overwhelming—there are so many features, installation methods, and regulations to consider. In the United States, one feature that often sparks curiosity is rigid lower anchors, also referred to as “rigid LATCH.” These are newer to the US market, but they've been around in Europe for decades! In this post, we’ll explain what rigid lower anchors are, how they differ from other types of LATCH connectors, and why many caregivers find them especially convenient.

Infant Car Seats With Rigid Lower Anchors: Are They Safer? Expert Guide

‍

What Are Rigid Lower Anchors?

Rigid lower anchors (or rigid LATCH) are metal connectors built directly into the car seat base. Instead of using a flexible webbing strap to attach to the car’s lower anchor points, the rigid connectors clip directly onto the vehicle’s lower anchors. The LATCH system (Lower Anchors and Tethers for Children) was introduced to simplify car seat installation and reduce misuse. While the majority of car seats use flexible straps with hook or push-on connectors, rigid anchors are a specialized design that some manufacturers offer for their seats.

‍

What is the Difference Between Rigid and Flexible Lower Anchors?

Rigid lower anchors have solid arms that extend from the base or from the infant seat itself in some cases. Premium and basic lower anchors feature webbing that you have to tighten yourself. Rigid lower anchors are less work as they simply click onto the lower anchors and there is no manual tightening involved. Some rigid lower anchors have a pivoting arm that make it easier to get a good recline in the vehicle.

‍

Why Rigid Lower Anchors Can Be a Nice Feature

A child's car seat can be installed with the vehicle's seat belt or with the car seat's lower anchors. Ease of use is one of the main advantages of rigid lower anchors. The anchors just click into place so it's easy to confirm that the connection is secure. Studies show that correct installation is critical for optimal crash performance. Rigid anchors can reduce the chance of an improperly tightened seat, improving the seat’s performance in a collision. Rigid anchors create a very firm connection to the vehicle’s seat, which can help minimize side-to-side movement. The more stable the car seat, the more effectively it can protect a child. With rigid anchors, uninstalling the seat can be as easy as pressing a release button and pulling the seat out, which is convenient for caregivers who frequently move the seat between vehicles.

Tips for Installing Seats with Rigid Lower Anchors

1. Consult the Manuals

• ‍‍Always refer to both your car seat’s instruction manual and your vehicle owner’s manual. Proper alignment of the car seat base with the vehicle seat is crucial.

2. Listen for the Click

• Make sure you hear and/or feel a solid “click” when the connectors attach to the car’s lower anchors. If you don’t, the seat may not be properly secured. Some of the seats with rigid lower anchors have an indicator that turns green if the connectors are attached properly.

3. Check for Movement

• Once installed, test for movement at the belt path. The seat base should not move more than one inch side-to-side or front-to-back.

4. Level Indicators

• Many infant seat bases and infant seats have a built-in level or recline indicator. Ensure that your seat is at the correct recline angle for your infant’s age and size.

5. Schedule a Car Seat Check

• If you’re unsure about the installation, consider visiting a certified Child Passenger Safety Technician (CPST) for a thorough check. You can book a virtual consult with Safe in the Seat or you can try to find one local to you.
