The New Evoluna i-Size 2 and 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. Therefore offering maximum safety and convenience.

With its generous size and flat lying position as well as the adapting to the size of the baby, it is a great alternative to a carrycot.

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

A newborn's neck muscles are not fully developed, the head can easily roll forward whilst sleeping which can lead to breathing problems and potentially to lower oxygen saturation.

This can be minimised by a flat lying angle available in the car as well* simply by turning the handle and the slatted frame within the infant car seat is moved into a flat lying position which also absorbs the energy in the event of an accident or uneven roads and protects the sensitive spine of the baby.

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


How does it work?

The Evoluna i-Size, has unique patented Kiddy Lie-Flat Technology (KLF) 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,  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.

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

Other Features

Maximum side impact protection
The energy absorbing layer inside the baby shell as well as the 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 size of the baby through the newborn inlays and the adjustable 5 position harness system. It is generously sized and accommodates larger babies too.

Large sun canopy
The large sun canopy is fully adjustable meaning 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, and green indicators show whether the seat is engaged correctly.

Parenting 2018 

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

Since May 2015 The Lullaby Trust and Kiddy have worked in 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.

The 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.”
