One travel day
Where a seat on wheels earns its keep.



Check-in
The queue is long and the pram is already checked. Belt them in, and the suitcase does the standing.
Security
A three-digit TSA lock, no key to lose. Front pocket on the Plus for the tablet, the snacks and the passports.
The gate
Delayed. Every seat taken. Yours rolls with you and holds 100 kg, so the grown-ups sit too.
The Plus range
Top-opening. Brakes. A pocket for the snacks.
Watch the Carry On Plus and Check In Plus do the things the originals could not: open vertically, hold still while a child climbs on, and keep the tablet within reach.

Our story
Two parents, one airport, a better idea.
MiaMily started in 2014 when Alessandro Cereda and Cecilia Tsai, travelling with their own children, decided the suitcase should do more of the work. Swiss precision, real-life parenting insight, and a promise that travel with kids can be calmer.

Is the ride-on seat safe for children?
Yes, within its limits. The luggage has an aluminium frame rated to 100 kg and a wider base for stability, and the Carry On, Check In, Carry On Plus and Check In Plus include a built-in safety belt to secure your child. Children must be able to sit unassisted and should always be supervised by an adult. Use it on flat surfaces only, never on escalators or stairs.
Can I bring MiaMily luggage on a plane as cabin baggage?
The Carry On size is designed to fit in most airline overhead compartments. Airline cabin policies and weight limits vary, particularly on Australian domestic carriers, so we recommend confirming your carrier's dimensions before flying. The Check In and Check In Plus are checked luggage.
What warranty comes with MiaMily luggage in Australia?
Every MiaMily suitcase bought from an authorised Australian retailer is covered by a Limited Lifetime Warranty on manufacturing defects in materials and workmanship, covering zips, handles, wheels, stitching and materials. Wear and tear, cosmetic damage, misuse and airline handling damage are not covered. Claims go through the Coolkidz support portal with proof of purchase.
Which model should I buy?
Carry On for short trips and one rider. Carry On Plus if you fly often with a toddler and want top-opening packing, a brake and a snack pocket. Check In or Check In Plus for longer holidays and more than one child. Carry On Pro for teens and adults who want a light, front-opening case with a gate seat. The Which MiaMily page walks you through it in four questions.
