How to Install Clek Olli Booster Seat: A Simple Step-by-Step Guide

The Clek Olli is a popular backless booster seat known for its slim design and advanced safety features. Proper installation is crucial to ensure your child is protected on every journey. This guide walks you through the entire process, from positioning the booster to securing the seat belt correctly.

Unlike forward-facing car seats, boosters rely on the vehicle's seat belt to restrain your child. Therefore, correct positioning and belt routing are essential. Follow these steps carefully to get the most out of your Olli booster.

Before You Begin: Check Compatibility and Positioning

First, ensure your child meets the Olli's requirements: typically, children should be at least 4 years old, weigh between 40 and 100 pounds, and be 38 to 57 inches tall. Also, verify that your vehicle's seat belts are compatible with booster seats—most lap-and-shoulder belts work, but check the owner's manual if unsure.

Place the Olli directly on the vehicle seat, ensuring it sits flat and flush against the seat back. The booster should not overhang the seat edge. If your vehicle has headrests, adjust them so they don't interfere with the booster's back or the child's head support.

• Always use a lap-and-shoulder belt, never a lap-only belt.
• The booster must be used on a forward-facing seat; never use it with a rear-facing seat.

Step-by-Step Installation Process

Once the booster is positioned, have your child sit on it. The booster's back should be against the vehicle seat, and your child's back should be flat against the booster. Ensure the child's knees bend comfortably over the edge of the vehicle seat.

Now, pull the shoulder belt across your child and buckle it. The lap belt should lie low across the upper thighs, not the stomach. The shoulder belt should cross the center of the shoulder and chest, away from the neck. If the belt sits too high or low, adjust the vehicle's seat belt guide or use the Olli's built-in belt guides, if available.

Check that the belt is snug—you should not be able to pinch any slack at the hip. Also, ensure the belt is not twisted. The Olli's design helps position the belt correctly, but always double-check.

• If the vehicle seat belt has a locking retractor, engage it to prevent the belt from loosening.
• The Olli can be left in the vehicle when not in use; just secure it with the seat belt to prevent it from becoming a projectile.

Securing the Olli in Your Vehicle

While the Olli is a backless booster, it still needs to be secured when the child is not in it. Use the vehicle's seat belt to buckle the booster in place, or store it in the trunk. This prevents it from sliding during sudden stops.

If you have multiple vehicles, the Olli is easy to move because it's lightweight. However, always re-check the installation each time you move it. Also, consider using a non-slip mat under the booster if your vehicle seats are slippery, but ensure it doesn't interfere with the booster's stability.

Common Mistakes to Avoid

One common mistake is using a booster with a lap-only belt, which is unsafe. Another is placing the shoulder belt under the child's arm or behind the back—this defeats the purpose of the booster. Always ensure the belt is correctly positioned.

Also, avoid using the Olli with a seat that has a deep bucket shape if the booster tilts. The booster should sit level. Finally, never use a booster with a child who is too small—wait until they meet the minimum size requirements.

Cleaning and Maintenance Tips

To keep the Olli in top condition, wipe it down with a mild soap and water solution. Avoid harsh chemicals that could damage the plastic. Check the booster regularly for cracks or wear, and replace it if any damage is found.

If you need replacement parts, Clek offers various accessories. For example, the Foonf/Fllo Harness Covers are not for the Olli, but you can find compatible accessories on the Clek website. Also, consider the drink-thingy for olli to keep your child's beverage within reach during long trips.

Installing the Clek Olli booster seat is straightforward when you follow these steps. Always prioritize safety by ensuring a correct fit and proper belt routing. For more information or to purchase the Olli, visit the Clek website to explore our range of booster seats and accessories.
