The new i-Size infant car seat with a globally unique lie-flat function - even inside the car.

The Evoluna i-Size 2, along with its predecessor model the Evoluna i-Size, are the only infant car seats on the market to include the world’s first lie-flat function inside and outside the car and thus offer maximum safety and convenience.

With this lie-flat function, they define a new category of infant car seats and set a new global safety benchmark.

The predecessor model was convincing in the Stiftung Warentest and ADAC child car seat test in June 2016. Amongst the 26 tested child car seats, the infant car seat was the only one to achieve a "very good" (1.5) test score (The best ever recorded).

The Evoluna i-Size 2 meets the latest and stricter ECE-R129 (i-Size) standard; intensively testing front and rear impacts, rollover situations, and side impacts.

The optimized side impact protection as well as the one-click attachment to the Kiddy Isofix Base 2 not only make this infant car seat secure but also highly user-friendly.

With its generous size and flat lying position as well as the individualized adaptation to the size of the baby, it is a convenient alternative to the carrycot for buggies.


Unique lie-flat function for maximum safety and comfort.

The tested and patented technology by Kiddy (Kiddy Lie-Flat) was specially developed for the needs of newborns and premature infants.

Since their neck muscles are not fully developed yet, the head can easily tip to the front while sleeping which can lead to breathing problems and potentially to lower oxygen saturation.

This can be prevented by a flat lying angle. The Evoluna i-Size 2, along with its predecessor model the Evoluna i-Size, are the only infant car seats that offer this unique lie-flat function in the car as well*. By turning the handle, the slatted frame within the infant car seat is moved into a flat lying position.

The slatted frame also absorbs the energy in the event of an accident or uneven roads and protects the sensitive spine of the baby.

Pediatricians and midwives recommend the lie-flat position especially for longer journeys as this ergonomic position is better for the child’s developing spine.

*Please note that the Evoluna i-Size 2 requires at least 73.5 cm of space when in the reclined position.

Please check the front passenger legroom before installing the Evoluna i-Size in the lie-flat position.

Maximum side impact protection
The energy-absorbing layer integrated inside the baby shell, as well as the additionally fixed side impact protection components consisting of EPO (expanded polyolefin) ensure we achieve maximum side impact protection. Together with the protective components that can be attached to the side via the handle, the infant car seat absorbs the collision forces during a side impact before they reach the sensitive parts of the body of the baby.

Perfect for any size
The Evoluna i-Size 2 can be adjusted to the individual size of the baby through the newborn inlays and the adjustable harness system in 5 positions. It is generously sized and therefore perfectly suits larger babies, too.

Large sun canopy
The large sun canopy is fully adjustable. Thanks to the optimised fastening of the sun canopy to the infant car seat, the baby is even better protected against sun and wind.

One-click attachment – simple and safe
The Evoluna i-Size 2 infant car seat in combination with the Kiddy Isofix Base 2 can be easily installed. One click attaches the seat to the base, whilst green indicators show whether the seat is engaged correctly.


Kiddy are working in partnership with The Lullaby Trust to promote safer sleep for babies

In May 2015 The Lullaby Trust and Kiddy launched a partnership to promote The Lullaby Trust’s key advice on how to reduce the risk of Sudden Infant Death Syndrome (SIDS). The Lullaby Trust is the leading charity working to promote safer baby sleep, support bereaved families and raise awareness of SIDS.

Kiddy and The Lullaby Trust are working together to highlight the importance of lying babies flat whilst sleeping. As well as promoting The Lullaby Trust’s key advice on safer baby sleep, Kiddy will also be donating £10,000 to The Lullaby Trust through sales of the Evoluna i-Size which is an infant carrier with a lie-flat travelling function. This donation will go towards ensuring new parents receive crucial advice on how to keep their babies safe during sleep as well providing much needed funds to support bereaved families.

Francine Bates, Chief Executive at The Lullaby Trust commented: “The Lullaby Trust supports the Kiddy Evoluna i-Size infant carrier with its lie-flat travelling position for a baby. Our advice is that the safest place for a baby to sleep is on their back in a separate cot or Moses basket. 

“Car seats are not recommended for long sleeps, but when baby is out and about we would always recommend that he/she sleeps in the flattest possible position. We are delighted to see that the Kiddy Evoluna i-Size offers a solution to this problem.”

Chris Grech-Cini, UK Country Manager for Kiddy added: “We are delighted that the Lullaby Trust has identified the Evoluna i-Size as being unique on the market, in that, it overcomes the health issues associated with typical infant carriers thanks to our Lie-Flat technology. Kiddy has partnered with the Lullaby Trust in their mission to generate awareness of Safer Sleep for Babies.”

How does it work?

The Evoluna i-Size, has unique patented Kiddy Lie-Flat Technology (KLF) technology which enables the infant carrier seat to be moved into two positions: an upright position or a lie-flat position. When the handle is moved backwards, a slatted frame inside the infant carrier lifts up and gently moves the infant into a flat lying position. This flat position allows the child's body, neck and head to lie inline, thus keeping their airway open. The impact-absorbing slatted frame facilitates air to circulate evenly around a child's body, which helps to regulate their temperature, all year round.


Kiddy Lie flat technology

Grows with your child

The Evoluna i-Size is highly adjustable for any baby from newborn to 15 months. The newborn baby is gently supported by the newborn inlay (pink in the third image below) which can be removed as the infant grows. There are 5 shoulder height positions and a one pull adjustable 3 point harness to ensure a perfect fit every time.

There is a separate premature-inlay available (grey in the picture below) which will securely cradle a tiny premature baby to keep them safe and secure when travelling.



The Evoluna i-Size as a travel system

On arrival at your destination, your little one can continue to snooze outstretched in their Evoluna i-Size. Simply lift the infant carrier onto a compatible pushchair of your choice, and your baby will continue to sleep peacefully and safely. The lie-flat position offers the same benefits as a carrycot or lie-flat pushchair seat for the child's breathing, heart rate and skeletal systems.

The Evoluna i-Size fits using adaptors onto the Kiddy City'n Move stroller; or onto another brand of pushchair such as Babystyle, iCandy, Baby Jogger, Joolz, Bugaboo or UPPAbaby (see the Pushchair Compatibility Checker below..)
