Maintenance and Care
Proper maintenance ensures the longevity and hygiene of your Cybex LEMO High Chair.
- General Cleaning: All surfaces, including the seat and tray, are wipeable. Use a damp cloth with mild soap and water to clean. Avoid abrasive cleaners.
- Snack Tray: The Snack Tray is removable and dishwasher-safe for easy cleaning.
- Straps: The shoulder straps are easily removable for cleaning. The crotch strap can be more challenging to remove; consider cleaning it while attached to the Baby Set for a quick refresh.
- Wooden Components: If your chair includes wooden elements, ensure they are dried thoroughly after cleaning to prevent bulging or cracking. Food stains, especially from berries, may be absorbed if not cleaned promptly, as the wood is not perfectly sealed from the factory.
- Storage: Store the high chair in a dry place away from direct sunlight and extreme temperatures.
Troubleshooting
This section addresses common concerns you might encounter with your Cybex LEMO High Chair.
- Difficulty with Tray Removal/Attachment: The tray may require both hands to attach and remove. Ensure the clips are fully engaged or disengaged. If your hands are wet or messy, this can make the process more difficult.
- Suction Plates Not Sticking to Tray: The matte finish of the tray may prevent some silicone suction plates from adhering properly. This is a characteristic of the material.
- Loose or Damaged Parts: If any parts appear loose, broken, or damaged upon arrival or during use, discontinue use immediately. Contact Cybex customer service for assistance. Do not attempt to repair damaged components yourself.
- Strap Adjustment/Removal Difficulty: While shoulder straps are easy to remove, the crotch strap can be fiddly. Refer to the assembly instructions for proper removal and reinstallation.
