Always follow the instructions for a safe setup before use. Once assembled correctly, the durable materials make a great high chair and dining experience from their very first meal.
Adjusting the Convertible High Chair
The lift mechanism lets you quickly adjust the seat height for your child’s stage.
To adjust the height, make sure the high chair is empty and the harness is locked. Press the foot-operated button located on the base, then gently lift or lower the seat to the desired height. Release the button to lock the seat into place.
The adjustable height allows the Moon to fit under most standard dining tables as your child grows. The booster seat included can also be used for added height.
The flexibility is especially helpful for early feedings, bedside use, or positioning next to a nursing chair.
Footrest Adjustment
The adjustable footrest offers proper leg support during meals.
To adjust the footrest height, press the two buttons located on the sides of the footrest prongs at the same time. While holding the buttons, slide the footrest up or down to the desired position, then release to lock it in place.
The footrest attaches to the seat bar and can be removed by pressing both side buttons.
Recline Adjustment
The Moon high chair’s smooth sliding recline lets you quickly set the seat at the right angle for feeding or relaxing.
To adjust the recline, lift the lever located on the back of the chair. While holding the lever up, gently slide the seat up or down to your desired angle. Once positioned, lower the lever to lock the seat in place. The motion is fluid and quiet, allowing adjustments without bothering your child.
This feature ensures comfort from early months through upright sitting.
Adjustable Food Tray
The feeding tray is adjustable and removable for easy cleanup.
To adjust the tray on the feeding chair, align the slots underneath the tray with the safety bar and press down in the center until you hear a click. The tray can be removed for easy cleaning by pulling it away from the feeding chair, but it does not have multiple forward/backward sliding positions, allowing it to be used closer to the breakfast bar or dinner table. The tray is not dishwasher safe, but allows for safe, easy wipe clean.
Always lock the safety harness before making any adjustments to ensure the child’s safety.
Safety Features and Precautions
Safety is central to the Moon chair, offering stability and proper posture.

Weight and Age Guidelines
The mima Moon high chair is designed to grow with your child through every stage. From day one, it can be used in newborn lounger mode, providing a fully reclined position for infants. For added comfort and security, the baby headrest cushion should be used during the baby chair or lounging stage.
Once your child can sit upright, typically around 6 months, the Moon transitions into high chair mode, suitable up to approximately 3 years. Use the booster seat as they grow.
As your child grows, the high chair converts into toddler chair mode, for children up to 99 lbs (45 kg). During this stage, the junior cushion set can be added to provide extra comfort while also introducing a pop of color to complement your home.
Safe Use Guidelines
Always supervise your child and ensure the harness is fastened for a safe 90-90-90 sitting position during eating.
-
Always place the chair on a flat, stable surface away from walls, furniture, cords, or push-off points.
-
Before each use, confirm the seat is fastened to the base, and all locking mechanisms are fully engaged.
-
Do not use the chair if any parts are loose, broken, or missing; replace parts immediately to maintain safety.
Cleaning and Maintenance
Smooth, wipeable surfaces make cleaning the Mima Moon convertible high chair easy and help with daily maintenance.
-
Tray Cleaning: Clean the tray using a damp cloth and a mild cleaning agent.
-
Seat Pads: The seat pads can be wiped clean with a cloth or sponge for quick, routine care.
-
Booster Seat: Removable for convenience and designed to wipe clean easily with a damp cloth.
Its streamlined build minimizes crevices, while sturdy materials stand up to daily use, making it easy to keep the chair hygienic and long-lasting.
