Learn how to attach the Clek drink-thingy to your olli booster seat with simple steps, common mistakes to avoid, and tips for keeping it clean.
Quick Answer
To attach the Clek drink-thingy to the olli booster seat, align the holder's clips with the slots on the side of the seat and press firmly until they click into place. Ensure it's fully seated before each ride, and remove it for cleaning when needed.
The Clek drink-thingy for the olli booster seat is a simple accessory that adds a convenient cup holder to your child's booster. Designed specifically for Olli models, it clips onto the side of the seat in seconds, making it easy to keep drinks and snacks within reach without cluttering the car.
While the installation is straightforward, a few common mistakes can lead to a loose fit or a holder that pops off mid-drive. This guide walks you through the correct attachment process, highlights what to check before every ride, and explains how to clean the drink-thingy so it lasts for years.
Before You Start
Before attaching the drink-thingy, make sure your olli booster seat is properly installed in your vehicle. The drink holder attaches to the seat frame, not the vehicle seat, so the booster must be stable and correctly positioned. If your olli is new, the drink-thingy is included with the purchase, so you may already have it on hand.
Check the side of the olli seat for the attachment slots. The drink-thingy has two clips that align with these slots. If you're unsure which side to use, both sides are compatible, so choose the side that's most convenient for your child or the one closest to the door for easy access.
- Confirm your olli booster is installed correctly before attaching the drink-thingy.
- Choose the side that best suits your child's reach and your vehicle layout.
Step-by-Step Attachment
Hold the drink-thingy with the clips facing the seat. Align the clips with the slots on the side of the olli. Press firmly and evenly until you hear a click, indicating the holder is locked in place. Give it a gentle tug to confirm it's secure.
If the drink-thingy doesn't click into place, check that the clips are fully aligned and not obstructed by debris. Never force it—if it doesn't fit, remove it and try again. Once attached, place a cup or bottle in the holder to test stability before letting your child use it.
- Always listen for the click and test with a gentle pull.
- If it won't click, realign and try again—do not force it.
Common Mistakes to Avoid
One common mistake is attaching the drink-thingy to the wrong part of the seat. It only fits the designated slots on the side frame, not the armrest or the seat base. Attaching it elsewhere can damage the holder or the seat.
Another mistake is leaving the drink-thingy attached when cleaning the seat or when not in use. While it's safe to leave it on, removing it during deep cleaning prevents dirt buildup and makes the seat easier to handle. Also, always double-check the attachment before driving, especially after your child has been playing with it.
- Never attach the drink-thingy to any part of the seat other than the side slots.
- Re-check the holder's security before every trip.
Cleaning and Maintenance
The drink-thingy is dishwasher safe, but you can also wash it by hand with mild soap and water. Remove it from the seat, rinse off any spills or crumbs, and let it air dry completely before reattaching. This prevents mold and keeps the holder looking new.
Regular cleaning also helps maintain the clips' grip. Dirt and sticky residue can make the clips less effective over time. If you notice the holder becoming loose, clean the clips and the slots on the seat to restore a snug fit.
- Dishwasher safe, but hand washing with mild soap works too.
- Clean the clips and slots periodically to keep the fit secure.
Step-by-Step: Attach the drink-thingy to olli
- Locate the attachment slots: Look on the side of the olli seat for the slots designed for the drink-thingy. They are typically near the front of the seat, on either side. Checkpoint: If you can't find the slots, refer to your olli manual.
- Align the clips: Hold the drink-thingy with the clips facing the seat and align them with the slots. Ensure they are level and not angled. Checkpoint: Misalignment is the most common cause of a loose fit.
- Press until it clicks: Apply firm, even pressure until you hear a click. This indicates the clips are locked into place. Checkpoint: Give it a gentle tug to confirm it's secure.
- Test with a cup: Place a cup or bottle in the holder and make sure it sits securely. Shake the seat slightly to ensure the holder doesn't wobble. Checkpoint: If it wobbles, remove and reattach.
- Remove for cleaning: When needed, unclip the drink-thingy and wash it in the dishwasher or by hand with mild soap. Let it dry completely before reattaching. Checkpoint: Regular cleaning keeps the clips grippy and the holder hygienic.
