When you’ve got a crying baby – or a sleeping one – the last thing you want to do is fuss around with their car seat or stroller. In fact, wouldn’t it be amazing if their car seat became a stroller, with the click of a button? This was the thought process of Yoav Mazar, founder of the Doona – the world’s first infant car seat that transforms to a stroller in seconds, no additional parts required. The 2018 Doona Infant Car Seat surpasses every safety standard both in its primary function as a car seat and when converted into a stroller. With a deep double walled side impact protection, orthopedic inner cushion, and anti-rebound technology, the Doona is also larger than most of its peers, meaning that your infant can remain in the safest form of car seat longer.
