However, the Nuna Arra offers something quite unique that makes it stand apart: the car seat can recline to three different positions, including 157°, which is almost flat and makes it easier and more comfortable for baby to sleep in the car or if you're using the car seat as a pushchair modular attachment. Not so if you choose the Stokke Sleepi cot system, which starts as a tiny cot for newborns and can expand to become a larger cot for older babies, before expanding again – and again – with the child's growth to end up as a bed large enough to fit up until around the age of ten (at which point, you'd transition the child to a normal bed anyway).
