Learn how to install the Clek Foonf anti-rebound bar for rear-facing use. Step-by-step instructions, common mistakes, and replacement tips.
Quick Answer
To install the Clek Foonf anti-rebound bar, first remove the seat from the vehicle, then slide the bar into the rear-facing mounting points, and secure it with the locking pins. Always verify the bar is snug and level before reinstalling the seat. If you need a replacement, the Foonf Anti-Rebound Bar comes complete with sleeve and locking pins.

The anti-rebound bar is a key safety feature on the Clek Foonf when used rear-facing. It helps reduce the rebound motion that can occur in a crash, keeping the seat more stable. Installing it correctly is essential for it to work as intended.
Whether you're setting up a new Foonf or replacing an old bar, this guide walks you through each step. We'll also cover common mistakes and how to check that everything is secure.
Why the Anti-Rebound Bar Matters
When a vehicle is hit from the front, a rear-facing car seat can rotate toward the vehicle seat back. The anti-rebound bar presses against the vehicle seat to limit this rotation, reducing the forces on your child's neck and head. It's a simple but effective design that works with the Foonf's rigid shell.
The bar is only used in rear-facing mode. If you switch to forward-facing, you'll need to remove it. Always follow the manual for your specific model year, as the mounting points may differ slightly.
- Check the bar for damage before each installation.
- Keep the locking pins in a safe place when the bar is not in use.
Before You Begin
You'll need the anti-rebound bar, its locking pins, and the sleeve if your bar has one. If you're replacing a worn or damaged bar, the Foonf Anti-Rebound Bar includes the sleeve and locking pins, so you have everything in one package.
Make sure the Foonf is clean and dry. Remove any debris from the mounting points. It's also a good time to check the seat for any other wear, like frayed harness straps or cracked plastic.
- Work on a flat surface to avoid dropping small parts.
- Have the user manual handy for reference.
Step-by-Step Installation
Start by removing the Foonf from the vehicle if it's already installed. You'll need access to the bottom of the seat. Place the seat on a clean, soft surface to avoid scratching it.
Locate the two rear-facing mounting points on the underside of the seat. They are typically near the back edge. Slide the anti-rebound bar into these points until it clicks or sits flush. Then insert the locking pins through the holes to secure it.
Once the bar is in place, give it a firm tug to confirm it's locked. Then reinstall the seat in your vehicle, making sure the bar is pressed against the vehicle seat back. The bar should be level and not tilted.
- If the bar doesn't slide in easily, check for obstructions or misalignment.
- Never force the bar; it should fit snugly without excessive pressure.
Installation Steps at a Glance
- Remove the seat: Uninstall the Foonf from your vehicle and place it on a clean, flat surface. Checkpoint: Ensure you have clear access to the underside mounting points.
- Slide the bar into place: Align the anti-rebound bar with the rear-facing mounting points and push until it sits flush. Common mistake: Forcing the bar if it doesn't align. Adjust the angle and try again.
- Secure with locking pins: Insert the locking pins through the holes on both sides until they click. Checkpoint: Tug the bar firmly to confirm it's locked.
- Reinstall the seat: Place the Foonf back in the vehicle, ensuring the bar is pressed against the vehicle seat back. Common mistake: Leaving the bar tilted or not fully touching the seat. Adjust as needed.
