6 best lie-flat car seats from birth

Expert guide to innovative Group 0/0+ car seats that enable babies to sleep safely when out and about


Why lie-flat?

Research shows that it’s essential for healthy development that newborns lie flat for the majority of the time when they’re sleeping or lying down.


What does that mean for car seats?

In normal car seats, babies sit in a fairly upright position. Therefore, it’s recommended that babies stay in them for no longer than two hours at a time as their breathing may be compromised.  This 2 hour rule includes travel systems too.
