Yoav, founder of the Israel-based company, Simple Parenting, named the product after his daughter, Danielle.
He said: "When my wife and I had our first daughter, we felt the need to spend as much quality time with her and took her everywhere. While we understood the importance of protecting her, the day-to-day use of infant car seats and strollers was agonising.
"From my small designer's workshop, I set a clear goal in mind: To transform the infant car seat into something safe yet simple and practical."
The Doona has legs and wheels that fold up beneath it in a single motion, converting the stroller into a car seat.
It weighs 15lbs (7kg) and can be used as a seat in cars and aeroplanes, while two simple manoeuvres convert it back into a pushchair.
To unfurl the chair, parents need to undo a clip and pull upwards. Collapsing it again is slightly more labour intensive as there are four steps.
While there are plenty of 'compact' options deigned to free-up boot space, they all require that pieces un-clip and wheels have to be separately stowed.
But The Doona's folding mechanism is designed to be simple so it can be operated by one parent without any complications.
The Doona is secured using a 3-point seat belt, and it can also be installed with a Doona ISOfix base (sold separately).
The Doona costs £299 and is available in seven colours. You can pre-order from
