Cosatto On the Go Travel Car Seat
What age/height is the On The Go suitable for?
The On The Go seat is approved from 76cm (approx. 15 months) up to 150cm (around 12 years). This means it grows from toddler stage all the way to pre-teen adventures.
Is the seat i-Size compliant?
Yes. On The Go meets the latest R129 i-Size safety standard, including side-impact and rollover testing, providing enhanced protection as your child grows.
Can I use it rear-facing?
No — the On The Go is forward-facing only. It is designed as a compact travel seat for toddlers upwards, rather than a birth seat.
How does installation work?
It installs with:
ISOFIX + top tether from 76–105cm (up to 20kg)
Vehicle seat belt only or belt + ISOFIX (ISOFIT) from 100–150cm
This flexibility makes it ideal for taxis, hire cars, holidays, grandparents’ cars, and travel abroad.
Does it really fold up?
Yes! On The Go is the world’s first ultra-compact, foldable i-Size travel seat. It folds neatly and includes a carry bag, making airports, hotels, and quick trips far easier.
Is it suitable for flights / holidays?
It’s designed specifically for travel, with a 5.7kg lightweight fold. While not certified for aircraft seating, most families use it for:
airport transfers
taxis
rental cars
hotel runs
multi-car use
Does it include a harness?
Yes. From 76–105cm, children use the 5-point plus Anti-Escape harness — a Cosatto exclusive system designed to reduce wriggling and prevent escapes.
When can my child switch to seat belt mode?
From 100–150cm, On The Go functions as a high-back booster using the vehicle’s seat belt (with optional ISOFIT for extra stability).
Is the seat safe for side-impact?
Yes — On The Go meets mandatory R129 side-impact testing and includes Cosatto’s advanced SIPS (Side Impact Protection System) for added reassurance.
Does the cover come off for washing?
Yes. The seat features removable, machine-washable fabrics, ideal for travel spills and snacks on the go
