safety 1st sentinel ii convertible car seat is rated 5.0 out of 5 by 5.
Rated 5 out of 5 by from easy and value for money My 5 mth old baby falls asleep it's so comfortable. Lots of padding and fabric is very soft. She didn't in the capsule I had before this. Seems stirdy and safe and is easy to install. Loved that you can adjust the height of the harness so easily as my daughter is tall and is growing very fast. Would buy it again for sure and happily recommend

Rated 5 out of 5 by from Adore this car seat! I have purchased this same car seat twice from harvey norman big buys for both my babies. It is the most easy car seat to install and what I love most is how comfortable the seat is. Both my children sleep in and love their car seats. The covers come off so easily to wash and put back on! I have purchased a different brand car seat and was not happy so I sold it. Will definitely be buying another one of these for baby number 3!!

Rated 5 out of 5 by from Safe, Stylish & Practical The material is so velvety & smooth, it feels so soft? Excellent amount of padding but still breathable for bub. I find it very easy to use & the safety reviews make me confident in the product. The 'night' colour (black) looks super smart & stylish in my car. I'd certainly recommend this car seat to anyone.
