I was looking for something suitable for quite a while and this works well!
I wanted a protector with some firmness / density in its construction to prevent indent damage from the moulded child restraint frames onto the actual car seat base and back rest. This does the job.
The base piece plastic and not fabric so is perfect to wipe down and the fold down at the front to stop little people’s shoes marking the front edge of the seat is an added bonus.
Great that you can use IsoFix with it too.
The back rest has a soft padded fabric cover and also does the job of preventing indent damage.
It will be comfortable for the child if they move on to a base only booster.
Would have been great for the NZ / Australian market to have had another piece which could attach to the backrest and go between the top of the car seat and headrest to stop the anchor strap from squashing the top of the car seat when in use.
Perhaps in the U.S.A their car seats do not utilise an anchor strap?
All in all, I can highly recommend this product.
