Travel system: trio, duo or just bassinet? How to choose

Irene · May 24, 2026 · 9 min

The question “trio, duo or just bassinet?” is one of the most anxiety-inducing steps when preparing for a baby's arrival. We're talking serious money (300-900 €), an object you'll use every day for 3 years, and decisions that depend heavily on your real lifestyle. This guide explains what changes between the three options, when each is worth it, and the most recommended models in every price range.

What “trio”, “duo” and “bassinet” really mean

Before choosing, let's clarify the terms. These are European terms used by manufacturers, but they don't always mean the same thing across different catalogues.

Trio (3-in-1 travel system): includes 3 pieces on the same chassis — stroller frame + bassinet (for newborns 0-6 months, lying flat) + group 0+ infant car seat (for the first 12-15 kg). There's often also a reclining toddler seat for the stroller, facing parent or world, from 6 months onwards.
Duo (2-in-1 travel system): same chassis + bassinet + toddler seat. No car seat included. Suited to those who buy the car seat separately (perhaps from a specialist brand like Cybex, Britax, Maxi-Cosi) or to those who don't need one (mainly urban use, no private car).
Standalone bassinet: just the lie-flat carrycot for newborns 0-6 months, mountable on a compatible stroller frame. Includes nothing else. It's the choice for those who already have a chassis or want to build a modular system by assembling pieces from different brands.

The 4 factors to decide

The right system depends on how you will use the stroller. Four questions guide the choice better than any comparison chart.

1. How much will you use the car in the first 12 months?

If you live in a big city, have a family car but use it 2-3 times a week, the trio is the most convenient choice: the car seat detaches from the stroller chassis and clips into the car without waking the baby. If you live in less urban areas or use the car every day, the trio is an even stronger pick for the same reason.

If you live in a historic city centre and only take the car on weekends or in emergencies, a duo + separate car seat is often a better choice: the dedicated car seat is safer and lasts more years (group 0+/1 up to 4 years), while the one included in the trio maxes out at 13 kg (group 0+ only) and needs replacing.

2. How many kilometres will you walk?

If you walk a lot (parks, daily strolls, walking to the supermarket), the weight and manoeuvrability of the chassis matter more than anything else. Look for frames under 10 kg, with shock-absorbed wheels, a height-adjustable handle and one-handed folding. Heavy frames (12-13 kg) look sturdier but become a torture after a few months. Find lightweight shock-absorbed strollers on Amazon

3. How much space do you have to store it?

Measure the boot and the spot where you'll keep it at home before buying. A folded trio takes up on average 70 × 50 × 30 cm. Some models fold compactly in half (Cybex Mios, Bugaboo Butterfly, YOYO Babyzen) and fit in an airplane overhead bin. Others are huge and take up the entire boot. Find cabin-sized compact strollers

4. What's your budget?

Value for money changes a lot by price bracket:

300-450 € — entry-level trio (Inglesina, Foppapedretti, Cam). Great for those who want a functional system without frills. Slightly heavier frame, but everything works. Find entry-level travel systems on Amazon
450-700 € — mid range (Chicco Best Friend, Peg-Pérego, Bébé Confort). Lighter frames, better materials, quieter wheels. Find Chicco Best Friend / Peg-Pérego
700-1100 € — premium (Cybex Mios, Bugaboo Fox, Stokke Xplory). An investment for those who really walk a lot and/or want top-tier aesthetics and durability for more than one child. Find Bugaboo / Stokke / Cybex

When the trio is worth it

The trio (3-in-1) is the right choice if at least 2 of these conditions apply to you:

You use the car frequently (at least 3-4 times a week).
You value the “everything included” convenience of a single box.
You want to simplify decisions (chassis, bassinet and car seat already matched and tested together).
You don't want to mix different brands.
This is your first child: the accessories stay for future siblings.

The limit of the trio is that the included car seat is almost always a “lightweight” group 0+ (up to 13 kg / about 15 months). At that age you'll still need to buy a next-stage car seat (i-Size 76-105 cm or group 1).

When the duo (without car seat) is worth it

The duo is the most rational choice if:

You want a safer and longer-lasting car seat than the one included in the trio. The best i-Size car seats (Cybex Cloud T, BeSafe iZi Go Modular X1, Maxi-Cosi Pebble 360) are on average better than the base models included in mid-low trios. Find i-Size 0+ infant car seats
You rarely use the car (urban life, public transport, work 10 minutes on foot).
You already have a compatible car seat (from an older sibling) or you're willing to buy one separately.

The price difference between trio and duo is on average 80-120 €. At that price, the car seat included in the trio is an entry-level “gift”. If you want a better one, choose the duo and invest the 120 € saved into a top-tier car seat.

When just the bassinet is worth it

A standalone bassinet is a niche choice, but justified in 3 scenarios:

You already have a compatible chassis (from a sister, a cousin, bought second-hand): in that case adding only the bassinet saves you 200-300 €.
You want to build a mix-brand modular system: for example a Bugaboo chassis + Bugaboo bassinet + Cybex car seat. Often you can achieve the best possible setup, even if pricier.
You're on your second child: the first child's stroller is still great, but you need the bassinet because the first one only had the toddler seat. Find compatible bassinets

Three details that change the daily experience

Wheels: solid or air-filled?

Solid rubber wheels (EVA or polyurethane) don't puncture, require less maintenance, but absorb bumps less. Air-filled wheels roll better on gravel, cobblestones, uneven tiles — but they can puncture and need pumping every 2-3 months. For urban use you're right to choose solid rubber; for mixed city + parks/off-road use, prefer air-filled.

Height-adjustable handle

It seems like a detail, but if you're 160 cm and dad is 190 cm, an adjustable handle saves you years of back pain. Most trios over 500 € include it. Below that it's less common.

Reversible seat

All modular systems let you turn the toddler seat parent-facing or world-facing. It's an option you'll actually use a lot in the first 12-18 months: the baby wants to see you when sleeping, then wants to look at the world when awake. Always check it's included before buying.

What to check in store or on delivery

One-handed opening/folding: must work even with the baby in your arms.
Chassis weight: try lifting it as you would to put it in the car.
Underseat basket: must be roomy (handy for shopping and the changing bag).
5-point seat harness, with soft padding on shoulders and groin.
Canopy with removable visor and peek-a-boo window to check on the baby without leaning over.
Warranty: minimum 2 years, ideally 5 (Bugaboo, Stokke, top-of-the-range Cybex).

Tip: stroller as a group gift

The stroller is the most expensive item in the baby kit and almost always out of budget for a single gift. The most dignified choice is to add it to the baby registry as a group gift: 3-5 people contribute together with the amount they choose, and the item gets covered without embarrassment. It's exactly the kind of item this feature exists for.

In summary

Trio → family with frequent car use, first-time parents, 400-700 € budget, you want to simplify decisions.
Duo + separate car seat → urban life, you want a top-of-the-range car seat that lasts longer than the base model included in the trio.
Just the bassinet → you already have a compatible chassis or you're building a mix-brand setup.

Whatever you choose, remember to try it open and folded before taking it home, and check that your car's boot is compatible. It sounds obvious: in reality it's one of the most frequent reasons for returns in the first 7 days.
