The Croozer Yuuna Kid Module: Basic Seat is an ergonomic child seat module that clicks into the Croozer Yuuna trailer chassis.

Croozer Yuuna Kid Module: Basic Seat

The Yuuna Kid Module: Basic Seat is Croozer's ergonomic child seat for the Yuuna trailer chassis. It carries one child from around 12 months (once they can sit upright unsupported) up to 4 years or 18 kg, with a five-point harness and a height-adjustable, removable headrest.

The seat clicks straight into a Yuuna via Croozer's module system — no tools, no re-fit. It runs on the left or right cabin position, so you can pair two basic seats for two children, mix it with a Premium Seat or a Baby Lounger, or swap in a Cargo or Dog Module later. The seat surface is CLIMATEX® — a polyamide/wool/viscose blend that helps regulate temperature and moisture on hot rides.

Fits the Croozer Yuuna only. Not compatible with older Croozer models (Kid Vaaya, Kid Keeke) or with Kid Lykke.

Pro tip

If you're carrying two kids close in age, two Basic Seats fit the Yuuna cabin side-by-side and pack down together for a smaller boot footprint. Keep the Yuuna Module Lock (article 122700025) in your pocket — the seat clips out fast, and left in a busy café rack it's a five-second grab.

What's in the box

Yuuna Kid Module: Basic Seat — Foldable child seat with headrest and Climatex® finish
Five-point harness — Pre-fitted to the seat

Will it fit

The Basic Seat is a Yuuna-only module — it will not fit a Croozer Kid Vaaya, Kid Keeke, Kid Lykke, or any pre-Yuuna Croozer chassis. It clicks into either cabin position without tools, so you can combine it with a Premium Seat, Baby Lounger, Cargo or Dog Module on the other side, or run a second Basic Seat for two children. Pairs with the Croozer Yuuna Premium Modular Bike Trailer — this seat slots into Kid mode on that chassis.

Choose if

You own — or plan to buy — the Croozer Yuuna, and you want the most affordable Yuuna kid seat.
You'll switch between kid, cargo and dog modes and don't need the Premium Seat's reclining backrest.
You want a second seat next to a Premium Seat or Baby Lounger for two children.

Not ideal if

You own an older Croozer (Kid Vaaya, Keeke, Lykke) or a non-Croozer trailer — this will not fit.
Your child is under a year and can't yet sit upright unsupported — the Baby Lounger is the correct module for babies.
You want a reclining backrest for a napping toddler — that's the Premium Seat (110°/130° angle).

FAQ

What age is the Basic Seat for?

From around 12 months (once the child can sit upright unsupported) up to 4 years or 18 kg / 1.05 m — whichever comes first.

Does it fit any bike trailer?

No — the Basic Seat clicks into the Croozer Yuuna chassis only. It won't fit Kid Vaaya, Keeke or Lykke.

Can I put two Basic Seats in one Yuuna?

Yes — the Yuuna's modular cabin takes two side-by-side, one on the left and one on the right.

Is the seat washable?

The seat cover is not machine-washable. Croozer lists it as 'not washable' — spot clean.

Can I lock the seat into the trailer?

Yes — the Yuuna Module Lock Kid (article 122700025) is a small ABUS combination padlock designed for this exact purpose.
