Learn how to easily attach or replace the tray on your Cosco Simple Fold High Chair. Step-by-step guide for installation and removal.
Quick Answer
Attaching a replacement tray to a Simple Fold High Chair is a straightforward snap-in process that takes under a minute when you align the tray arms with the chair's mounting posts.
Why You Might Need a Replacement Tray
Over time, high chair trays can become scratched, cracked, or stained from daily use. A worn tray may not snap securely, which can be a safety concern. The Simple Fold High Chair Replacement Tray (model HC225) is designed specifically for the Simple Fold High Chair, ensuring a proper fit and reliable performance.
If your original tray is damaged or missing, a replacement restores full functionality without buying a whole new chair. The tray is easy to install and remove, making mealtime cleanup simple.
Before You Start: Check Compatibility
The replacement tray is only compatible with the Cosco Simple Fold High Chair (model number HC225). If you have a different high chair model, this tray will not fit correctly. Verify your chair's model number on the label underneath the seat or on the frame before purchasing.
Step-by-Step Guide: Attaching the Replacement Tray
- Remove the Old Tray: Press the release buttons or levers on both sides of the tray arms simultaneously. Pull the tray straight out away from the chair. If the tray is stuck, gently wiggle it while pressing the releases. Common mistake: pulling only one side can warp the tray or damage the release mechanism. Always press both releases at the same time.
- Align the Replacement Tray: Hold the new tray with both hands. Line up the slots on the underside of the tray arms with the two mounting posts on the front of the high chair seat. The tray should be level and centered. Checkpoint: if the tray does not slide on easily, do not force it. Recheck alignment to avoid bending the posts.
- Snap the Tray into Place: Push the tray straight toward the chair until you hear a click on both sides. Give each arm a gentle tug to confirm it is locked. The tray should not wobble or slide off. Common mistake: stopping after one click. Both sides must lock for safe use. Test both arms individually.
- Adjust the Tray Position (if needed): The Simple Fold High Chair tray has a 3-position adjustable feature. To move it closer or farther from your child, press the release buttons and slide the tray to the desired position. Release the buttons to lock it. Checkpoint: always lock the tray in the forward-most position when your child is not eating to make getting in and out easier.
