During the first months, the spacious carrycot offers your newborn a fully lie-flat position, ideal up to approximately 6-9 months.

The extendable canopy with UPF 50+ UV protection offers effective protection from the sun, while two separately adjustable panoramic ventilation windows promote pleasant air circulation inside.

The carrycot mattress features a soft raised protective edge, designed to prevent your baby’s delicate head from coming into direct contact with the large panoramic ventilation window.

Thanks to the integrated Memory function, the carrycot can be released from the chassis with one hand.

It can also be folded quickly to take up less space during transport or when not in use.

Reversible seat with fully lie-flat position

When your child is able to sit up independently, you can switch to the included stroller seat.

The seat is reversible and can be installed:

parent-facing
world-facing

The padded backrest is adjustable in 3 positions, from the sitting position to the fully lie-flat position.

The footrest adjustable in 3 positions completes the comfort, allowing your child to sit, relax or sleep comfortably.

Canopy with UPF 50+ UV protection

The seat features a large extendable canopy with UPF 50+ UV protection.

An additional sun visor offers extra protection when the sun is low, while the integrated ventilation and viewing window promotes airflow and allows you to keep an eye on your child at all times.

Tulip i-Size car seat

The ABC Design Tulip car seat included in the set is suitable from birth up to approximately 15 months, for children from 45 to 85 cm.

It is approved according to ECE R129 i-Size and features side impact protection and a padded 3-point harness.

The removable insert, headrest adjustable in 4 positions and adjustable padding allow the car seat to adapt as your child grows.

360° rotating Root Isofix base

The included Root Isofix base allows the Tulip car seat to be installed in the car simply, quickly and safely.

The 360° rotation function allows the car seat to be turned towards the door, making it easier to place your child in the seat and fasten the harness.

The same base is also compatible with the Lily i-Size rear-facing car seat, which can be used in the next stage after the Tulip infant car seat.

Practical and quick Travel System

Thanks to the included adapters, the Tulip car seat can be attached directly to the Sierra chassis.

This allows you to move easily from car to stroller without waking your child, a particularly practical solution during the first months.

Compact fold

Sierra can be folded quickly to compact dimensions, even with the seat installed world-facing.

Two intuitive controls on the chassis allow the stroller to be folded easily, making it practical to store in the car boot or carry on buses and trains.

Large puncture-proof wheels

The large puncture-proof wheels, quality ball bearings and suspension contribute to a smooth and comfortable ride.

Sierra is suitable for:

paved roads
cobblestones
park paths
gravel routes
forest paths
country roads

The front wheels can be left in 360° swivel mode for easier manoeuvring in the city or locked on more uneven terrain.

Adjustable handlebar

The handlebar can be height-adjusted from 75 to 108 cm.

This feature allows the stroller to adapt easily to the height of the person using it, encouraging a more natural and comfortable posture.

Plenty of storage space

The spacious lower basket offers room for everything needed during outings with your child.

Thanks to the Universal-Fix attachment points, compatible accessories can also be attached easily, such as:

changing bag
cup holder
light
magnetic clips
