Learn how to install your Clek Oobr booster seat with the anti-rebound bar. Our step-by-step guide covers high back and backless modes, LATCH, and safety tips.

The Clek Oobr is a premium booster seat designed to grow with your child, offering both high back and backless modes. One of its standout features is the optional anti-rebound bar, which adds an extra layer of safety by reducing rebound motion in the event of a crash. Proper installation is crucial to maximize protection, and this guide will walk you through every step, whether you're using the high back or backless configuration.

Before you begin, ensure your vehicle is compatible with booster seats and that your child meets the minimum weight and height requirements for the Oobr. Always refer to your vehicle owner's manual and the Oobr instruction booklet for specific details. Let's dive into the installation process, including how to attach the anti-rebound bar and secure the seat correctly.

Understanding the Oobr Booster Seat and Anti-Rebound Bar

The Clek Oobr is engineered with safety and comfort in mind. It features a rigid LATCH system, energy-absorbing foam, and a steel frame. The anti-rebound bar is an accessory that attaches to the base of the seat, designed to minimize the rotational movement of the booster during a collision. This is particularly important in high back mode, where the seat's mass can otherwise pivot forward.

The anti-rebound bar is not required for booster use, but it is highly recommended, especially when using the Oobr in high back mode. It adds stability and reduces the risk of head and neck injuries by limiting rebound. When installing, you'll need to decide whether to use the bar based on your vehicle's seating and your child's comfort. The bar is sold separately, but many families find it a worthwhile investment for peace of mind.

  • Check your vehicle's seat belt and LATCH compatibility before installation.
  • Ensure your child meets the Oobr's weight and height limits: typically 40-100 lbs for high back mode.

Preparing for Installation: What You Need

Gather the necessary items: your Clek Oobr booster seat, the anti-rebound bar (if you have it), the vehicle's seat belt or LATCH connectors, and the instruction manual. It's also helpful to have a towel or blanket to protect the vehicle seat if needed. Make sure the booster is clean and free of any debris that could interfere with installation.

Before placing the booster in the car, adjust the headrest to the appropriate height for your child. The headrest should be positioned so that the middle of your child's ears is level with the top of the headrest. This ensures proper belt positioning and side impact protection. Also, check that the seat belt path is clear and unobstructed.

  • If using the anti-rebound bar, attach it to the bottom of the Oobr before placing the seat in the vehicle. Align the bar with the slots and push until it clicks securely.

Step-by-Step Installation: High Back Mode with Anti-Rebound Bar

Start by placing the Oobr booster on the vehicle seat, ensuring it is flush against the seat back. If your vehicle has adjustable headrests, remove or adjust them to allow the booster's headrest to sit flush. Then, if you have the anti-rebound bar, attach it to the base of the booster as described earlier. The bar should point toward the vehicle floor, not upward.

Next, secure the booster using either the LATCH system or the vehicle's seat belt. For LATCH, connect the rigid connectors to the vehicle's lower anchors. You'll hear a click when they are properly attached. For seat belt installation, route the lap belt through the belt path and buckle it, then pull the shoulder belt to tighten. Ensure the booster is snug and does not move more than one inch side-to-side.

Now, position the seat belt across your child. The lap belt should lie low on the thighs, and the shoulder belt should cross the center of the shoulder. Adjust the booster's belt guides to ensure proper fit. Finally, recheck that the booster is stable and the anti-rebound bar is securely in place.

  • Always use both the lap and shoulder belt for high back mode. Never use a lap-only belt with the Oobr.

Installing in Backless Mode (Without Anti-Rebound Bar)

When your child outgrows the high back mode (typically when their shoulders exceed the top harness slots or their ears are above the headrest), you can convert the Oobr to a backless booster. Remove the backrest and headrest, leaving just the base. The anti-rebound bar is not used in backless mode, so detach it if installed.

Place the backless base on the vehicle seat and secure it with the vehicle's seat belt. The lap belt should pass through the belt guides on the base, and the shoulder belt should lie across the child's shoulder. Ensure the base is stable and the seat belt is tight. This mode is ideal for older children, but always check that the child can sit properly with the belt positioned correctly.

  • In backless mode, the Oobr does not use LATCH; rely on the vehicle's seat belt for installation.

Common Mistakes and Troubleshooting

One common mistake is not tightening the seat belt enough, resulting in a loose booster. To fix, put your weight into the booster while pulling the belt to tighten. Another issue is improper anti-rebound bar attachment—ensure it clicks into place. If you encounter difficulties, refer to the Foonf/Fllo Troubleshooting Tool for general guidance, though it's designed for convertible seats, the principles of secure installation apply.

Also, check that the booster is not installed in a seating position with a front airbag, as this can be dangerous. If your vehicle seat is deeply contoured, the booster may not sit flush; use a rolled towel to fill the gap if needed. Always double-check the seat belt path to avoid twists that could weaken the belt.

  • If the anti-rebound bar interferes with the vehicle seat belt, adjust the bar's position or remove it—safety comes first.
