When reviewing booster seats, they focus on correct seatbelt positioning, ease of use and overall safety compliance with Australian Standards.

Firstly, the reason I bought this seat was because of its high safety rating for both the harness & booster seat setting . Though since buying Ive also fallen in love with the versatility of this seat. Being a grandparent I love how I can have the harness set for the 3 year old but quickly change it to a sash belt for the 5 year old when needed. I also like how slim line it is as I can still seat two other children in the back & the kids say it’s super comfy.
I purchased 2 of these seats for my daughters due to the high rating it got. My girls are happy with their new seats and of course cup holders and I am impressed with the extra padding on the seat compared to alot of other brands I looked at. My only real complaint is how much of a pain it is to install and the fact it uses the entire length of the seatbelt to do it..
I bought two seats for my daughter for our two cars. I was impressed by how little room it takes up in the cars! Much slimmer than her previous car seat. I’m very happy with the fact that she will be able to use this seat until she no longer needs one.
I bought this car seat for my 4 year old daughter. She said its very comfortable. I found installation a bit fiddly compared to other car seats but watched the installation video which helped. My experience with bubsngrubs was very good. The colour I ordered wasn’t available until mid June, however, another colour was sent out quickly. Thank you
We purchased two of these for our three year old daughter (one for each car). Bubs N grubs did the installation which was great. It has a great safety rating and is very well priced. My little one is petite and loves the insert to make the seat more comfortable for her. She also loves the cup holders. This seat will look after her until she no longer needs a car seat. We will be buying another couple soon for our son. Thanks bubs N grubs.
Overall I am very impressed with this seat. I chose it because it had a the best safety rating in its class on the independent testing site childcarseats.com.au. It’s compact, comfortable and my toddler loves the cupholders – as mentioned by others! I found it rather fiddly to install as you have to loop the seat belt through and around the seat, but we’ve only got the one car so now it is in, it’s staying in.
I called this the ultimate car seat for a couple of reasons 1) because it’s affordable 2) high quality
It’s so easy to install & light weight, the cup holders are a real plus.. the kids love them.
It’s nice to have a choice of colour too instead of just black or grey. The service by staff was very very good. Would definitely recommend this car seat and will definitely consider shopping again at bubsngrubs.

This is well priced. The best thing about this seat is it is slim line. So many seats are bulky and difficult to move around. I have a Mazda 3 and it fits nicely in the back with another baby seat. My daughter likes the cup holders.
We brought one of these when our second child needed an upgrade. Liked it so much we got another one for the second car. Easy enough to put in and doesn’t feel too wide.
You can’t really use one of those seat belt locking clips like on other seats like the Britax Compaq (our other seat). So its slightly trickier to take out and adjust but not that big of a problem.
My 4yr old going on 5yr old daughter loves the seat. Comfortable and can recline. She also loves the colour (chose red). I’ll be looking to purchase a 2nd seat later in the year for my 3yr old going on 4yr old daughter who is very close in height to her big sister. Plenty of to move and space between (Mitsubishi Triton Sports dual cab). The retractable cup holders are a novelty for my daughter who loves the fact she can put her water bottle in there. Easy enough to install – certainly no more difficult than most car seats. Take the time to read the instructions and it’s not an issue. Recommended!
