The Comfi Astra is a Convertible Booster Seat. It uses the in-built harness from approximately 6-months through to 4-years-old. After this, it converts into a Booster Seat with the vehicle’s lap & sash seatbelt once the child reaches the middle marker, which is outgrown at approximately 8-years-old. Comfi Astra features Air Cocoon Technology, which drastically reduces the impact forces during a crash, as well as Active Fabric covers. Comfi Astra features an inbuilt anti-submarine designing, meaning no additional crotch clips are required! The Pinch Test Because safety always has and is the number one priority for your little ones, a means of quickly checking whether your child's car seat or capsule harness is tight enough is a must. This is where the Pinch Test comes in. To begin, first adjust your childs harness to be nice and firm by pulling the harness adjuster at the front of the seat. Once this is done, try to pinch the harness at your child's upper chest or shoulder. If you can't pinch it the harness is fitted correctly and you're good to go. If you can pinch the harness then try to tighten it again, and repeat this process until you can no longer pinch it. This method is both simple and quick and can be done every time you put your child in their car seat!

Car seat is great but it was poorly wrapped in a flimsy torn clear plastic bag. Something this expensive should be boxed for delivery
Excellent!! product as expected. very satisfied.
Got it for my toddler who is obsessed with pink colour.. and finally she sits on her car seat without throwing tantrums ..
This car seat is perfect great clout very easy to install an my toddlers fits great
Love this product was easy to install and will last my daughter until she turns 8.
My daughter can loosen her belts by lift the leaver then leaning forward so the belts come loose. Very scary
Very happy with the product
