What is the Joolz Aer2 Cocoon?
The Joolz Aer2 Cocoon is an accessory designed to transform the Joolz Aer2 into a stroller suitable from birth. Instead of using a traditional carrycot, this system functions as a newborn cocoon integrated directly into the stroller.
The main advantage is allowing the baby to always travel parent-facing, maintaining constant eye contact during the first months of life.
Additionally, the Aer2 Cocoon can fold together with the stroller, which is rare in this segment.
Main Features of the Joolz Aer2 Cocoon
Use from birth
The newborn cocoon was developed for babies from their first days of life up to 15 kg.
The baby remains comfortable in an ergonomic and secure position, using an adjustable five-point harness.
Highlights:
- Compatible only with the Aer2
- Use up to 15 kg
- Baby always parent-facing
- Lightweight and compact structure
- Folds with the stroller
Integrated first-stage seat
One of the biggest advantages of the first-stage seat is its versatility.
When the baby no longer wants to lie completely flat, the Joolz seat easily transforms into a more upright position.
Adjustment is made via the back of the cocoon, allowing a quick transition from newborn mode to a first-stage seat.
Why is this system so interesting?
- Avoids buying a traditional carrycot
- Keeps the baby parent-facing
- Reduces the total weight of the stroller
- Facilitates travel and déplacements
How to Assemble the Joolz Aer2 Cocoon

The installation of the Joolz Aer2 Cocoon is extremely simple and intuitive.
Step-by-step assembly
- Attach the side pieces to the stroller frame
- Position the Aer2 Cocoon on the chassis
- Press until you hear it click into place
- Adjust the back structure
- Confirm the stability of the baby seat
The entire process takes less than a minute.
For parents who use the stroller daily, this speed makes a difference in everyday life.
Baby's Comfort in the Joolz Aer2 Cocoon

Baby always parent-facing
The fact that the baby remains parent-facing is one of the main highlights of this system.
Many parents prefer the parent-facing position in the first months because:
- Facilitates eye contact
- Increases the feeling of security
- Allows monitoring the baby
- Helps with daily interaction
Unlike many compact strollers, the first-stage seat maintains this position for a long time.
Extendable canopy with sun protection

The extendable canopy offers excellent coverage to protect the baby from the sun and wind.
The side structure easily attaches and creates a more protected area for the newborn's rest.
The canopy includes:
- Additional sun protection
- Side extension
- Integrated ventilation
- Deeper coverage
On hot days, ventilation significantly improves the baby's comfort.
Footmuff included
Another positive point of the Joolz Aer2 Cocoon is that it includes a footmuff.
This accessory helps protect the baby on colder days without the need for additional blankets.
Footmuff benefits:
- Protection against wind and cold
- Greater thermal comfort
- Better aesthetic finish
- Quick installation
The footmuff fits perfectly in the cocoon and matches the stroller's premium design.
Footrest: More Comfort as they Grow
When the baby grows and starts to use the sitting mode, the footrest becomes very useful.
This accessory improves the posture and leg comfort of the child.
The additional footrest allows for:
- Better leg rest
- More ergonomics
- Extended use of the seat
- Greater comfort on long walks
