3 in 1 prams and pushchairs grow with your baby by using different modules on one chassis: first a lie-flat carrycot for the newborn months, then a seat unit once your baby can sit up, usually from around six months. The car seat is used alongside for journeys by car. One set, no new pushchair to buy along the way, from birth to toddlerhood.
A pram with carrycot lets your baby lie completely flat, facing you. A pushchair has a seat unit for a baby who is ready to sit up and watch the world go by. Some of these terms describe the complete product, others just the module that clips onto the chassis – here’s how they compare:
| Term | Product or module? | What it is |
|---|---|---|
| Pram | Complete product | A wheeled cot for a newborn who lies flat, sold with a chassis. |
| Carrycot | Module | The flat sleeping module alone – clips onto a chassis, often removable. |
| Pushchair | Complete product | A wheeled seat your baby sits in, sold with a chassis. |
| Seat unit | Module | The sitting seat module alone – replaces the carrycot once the baby can sit. |
A 3 in 1 travel system is one chassis with three different attachments: a carrycot, a seat unit and an infant car seat. A 2 in 1 includes only the first two, while a 4 in 1 adds an ISOFIX base for the car.

A Venicci 3 in 1 pram pushchair combines three elements – carrycot, seat unit and infant car seat. Everything fits the same chassis – the carrycot and seat unit clip straight on, while the car seat attaches via adapters. The Venicci Upline 3 uses the Up2Go system, which lets the chassis fold together with the carrycot or seat unit still attached, in one motion. The Venicci Tila also uses the Up2Go system, and carries the same three parts in a lighter, more compact build for city life.
A fully flat position is the safest way for a newborn to travel and nap, and a carrycot is what makes it possible. Young babies can’t yet control their own heads, and their spines are too immature to support sitting upright for any length of time. Sitting up also puts a newborn’s breathing at risk: The Lullaby Trust, the UK charity behind safer-sleep guidance, warns that babies who sleep sitting upright for too long may develop breathing difficulties, and advises laying them flat on a firm surface instead. A newborn pram gives them exactly that on every walk.
A Venicci 3 in 1 pram with a car seat grows with your baby without you having to buy a new pushchair along the way – the seat unit is already part of the set, ready to swap onto the same chassis once your baby is ready. In the first months, your baby travels in the carrycot, lying flat on a firm mattress, facing you. Car journeys during this time are covered by the Venicci Tiago car seat, included in the bundle. From around six months, once your baby can sit up independently, the reversible seat unit takes over: starting off rear-facing so your baby faces you, then switching to a forward-facing as they get a bit older. Every Venicci chassis is rated up to 22 kg, well into the toddler years.
One chassis carries your child the whole way, from newborn to toddler. Every Venicci bundle also comes with a matching set of accessories from a raincover to a footmuff. You can also add extras yourself – adapters, parasols, spare wheels – from Venicci’s own accessories range as your baby’s needs change.

Venicci’s range meets all four: EN 1888 and EN 1466 certification for pushchairs and prams, i-Size (ECE R129/03) certification for car seats, all-terrain wheels with suspension and a ventilated carrycot.
One set, chosen well, grows with your baby from newborn to toddlerhood.
