Does the job


Great colours, daughter loves the pink and the cup holders. The booster does the job and it will adapt to her growth with the extendable head rest which is fairly easy to adjust. It's well made and the seat built guide is great. Easy to install and if you don't need it you can easily pop it in the boot so that an adult can sit in car and pop it back in the car when you need it for you child.
colour and size not too wide
a little pricey

Great slim line seat that my child loves


With baby three on the way needed safe but slim seat for my tall 5yo! He loves the seat & says itvis comfortable. I love the safety & slim design.
great for patents looking to fit 3 seats un back but not wanting to comprimise on safety.
nothing,was reasonably priced & now comes with height indicators.

Happy Safe and Sound!


The solution to our problem of 3 car seats across the back of a Ford Territory. Which (according to the carseat installer) is as wide across the back as a Prado - thought he was kidding until I tried it myself (in my friends car!). We currently have a Safe'n'sound capsule (hired), a Safe'n'sound Maxi rider AHR and the hi liner and whilst it is a little difiicult to do up the seat buckle the seat meets and exceeds all our expectations.
Size - we will not need another seat for our daughter and we will be able to hand it on to her youngest sibling when she is finished!
The harness is a little difficult to work out at first and can be a little fiddly but I'm sure over time we will become more adept at the process.

I was wondering what's the minimum Shoulder Height (i.e the Label A line) for this seat in cm? Also is there a minimum weight the child needs to weigh?

Kind Regards
