To convert the Chicco Stack 123 Chair from highchair to booster mode, remove the tray and the seat back. Then, detach the highchair legs. Attach the booster straps to the seat and secure it to a dining chair.
Use a damp cloth with mild soap to wipe down the plastic and metal parts. The seat pad can be machine washed on a gentle cycle. Make sure all parts are completely dry before reassembling.
To adjust the height, press the buttons on the legs and slide them to the desired position. Ensure both sides are even before securing the buttons in place.
Check if the tray is properly aligned with the attachment slots. If it is still loose, inspect the locking mechanism for any debris or wear. Clean or replace as necessary.
Yes, the highchair mode is designed for infants starting from 6 months old, with a 5-point harness for safety. Always ensure the child is securely fastened.
The chair can be disassembled for storage. Remove the tray, fold the legs, and detach the seat. Store all parts in a dry place to prevent damage.
Contact Chicco customer service for replacement parts. Provide them with the chair's model number and a description of the broken part.
While the chair is designed for indoor use, it can be temporarily used outdoors. Avoid prolonged exposure to sunlight and moisture to prevent material degradation.
Use the harness system provided, ensuring the straps are snug but not too tight. The buckle should be securely fastened, and the straps should lie flat without twisting.
The highchair mode supports up to 40 lbs, the booster mode up to 50 lbs, and the youth stool up to 60 lbs. Always check the weight limit before use to ensure safety.
