"Made travel so much easier! We took the TernX for our holiday vacation and it was clutch."
“Yes the price is high, but the headache of having a traditional stroller and it getting tossed around by airport staff makes it worth it. They've clearly done their due diligence with safety standards. If you can afford this luxury, go for it.”
“We watched and tried finding other solutions because of cost, but ended up just investing in 2 for our twins and our travels. We have been practising opening and closing! They are an amazing concept and very high quality.”

Will the airline let me board with it?
Folded it measures 55 x 35.5 x 23 cm, which sits inside the cabin-bag allowance for over 90 airlines, and it fits the overhead bin.
Most carriers class a stroller as a mobility item rather than cabin baggage, so in practice it usually travels in addition to your carry-on, and doesn’t cost you anything extra.
Note: Every airline has its own unique travel guidelines. To ensure an effortless boarding experience, we recommend checking with your carrier prior to departure.

The bags. The stroller. The child. Then security asks you to fold it down.
This is the airport juggle. The kids crying, emptying the bottom of the stroller to get it through security, and the extra backpack taken everywhere for their gear.

Travel strollers are too big and bulky. You'd have to bring a diaper bag, a carry-on and a separate stroller when traveling.

The family behind TernX
Hey, we're Tack and Hoe Ping. TernX didn't start in a boardroom. It started in a crowded airport terminal. Two exhausted parents juggling a diaper bag, a restless toddler, and luggage that was never built for family life.
We went looking for a stroller that could carry our gear, our little ones through airports and for daily outings. It did not exist, so we built it.
“Having children shouldn’t put a stop to your adventures.”
Tack and Hoe Ping, founders of TernX

FREQUENTLY ASKED QUESTIONS
Frequently Asked Questions
-
Will the airline actually let me board with it?
TernX's folded size, 55 x 35.5 x 23 cm, meets the published cabin requirements of more than 90 airlines, and most airlines classify it as a stroller rather than cabin baggage.
-
Does a stroller count as a carry-on?
Usually not. Airlines treat strollers as special items, so on most carriers TernX travels in addition to your carry-on allowance rather than using it up. Policies vary, so check your airline before you fly.
-
What happens if the overhead bins are full?
The same as any stroller: hand it to the crew at the aircraft door and it rides in the hold for that flight. Grab what you need from the compartment first. Nothing needs to be unpacked to fold it, and the hardshell keeps everything inside secure.
-
What ages does it fit?
It’s certified for children from 6 months up to 48.5 lbs (22 kg), typically around 4 years old. The backrest extends from 38 cm to 50 cm so it comfortably grows alongside your toddler.
-
Do I have to unpack it to fold it?
No. The fold is designed to work fully loaded. Everything stays inside the 18L compartment while you fold it, carry it and stow it, at security and at the gate.
-
Can I use it as my everyday stroller?
Yes. It was built for travel but engineered for daily use: front-wheel suspension, TPU wheels that handle sidewalks and shopping trips, a recline for naps, and the storage you’d normally push in an under-seat basket.
-
What if I change my mind?
You have 30 days from delivery. As long as it's unused and in its original packaging, send it back and we'll refund you, minus return shipping and a small processing fee. Head to our returns policy page to start a return.
