The Silver Cross Nia in Onyx Black is the world's only stroller that is IATA cabin-compliant in both seat and bassinet mode — making it the go-to compact travel stroller for families who refuse to check a bag. Lightweight at 15.7 lbs, suitable from birth to 55 lbs, and road-tested in our boutique for everyday use and international travel alike.
Travel-Ready Design
Nia folds with one hand, stands independently, and includes a built-in shoulder carry strap so you can manage baby and your carry-on without missing a beat. The folded dimensions of 9.5 x 17.5 x 21.5 in fit overhead compartments, compact car trunks, and packed train cabins with ease. A Magnetic Genius 2™ buckle and no-rethread harness make securing and releasing baby fast and frustration-free.
From Birth & Beyond
The lie-flat seat is newborn-ready from day one, and with an optional folding bassinet (sold separately) and car seat compatibility, Nia adapts as your family grows. The extendable UPF 50+ ventilated sun peak keeps baby shaded and cool whether you're navigating city streets or a resort pool deck.
Storage & Comfort
A supersized storage basket holds up to 22 lbs of essentials, and a seat pocket keeps your phone and keys within reach. Airy, crease-free fabric with soft cushioned vegan leather details means Nia looks as good as it performs — on vacation or on the school run.
