  • Britax Romer KIDFIX SL SICT Booster Seat is rated 4.4 out of 5 by 12.
    Rated 5 out of 5 by from Great car seat! I chose this car seat after doing lots of research and asking other people for their own experiences. The Which report was great as were all other reviews. The seat is easy to fit, my daughter seems to be comfortable in it and it's also easy to secure her correctly in the seat. I'm very pleased with my choice.

    Rated 4 out of 5 by from Safe and smart My daughter loves this new car seat, mainly because she gets to use a big girl car seat! It’s smart and boasts lots of safety features. Doesn’t look bulky. We’ve had our first big journey. She could sleep in it but definitely not as comfy as it could be. Would benefit from a slight recline setting.

    Rated 4 out of 5 by from Good seat This is a really good seat! Was a little tricky to fit in to my car with the isofix. Looks great fit both my 7 and 4 urology in as I bought 2

    Rated 3 out of 5 by from Not for me I ordered this and the recarro mona seatfix 2 after reading reviews on both on which, both scored highly but preferred the recarro one as more padding and looked more substantial. i returned this one

    Rated 4 out of 5 by from Good value Group 3 high back seat Purchased because of good safety review on 'Which'. This was easy to fit and my 4 year old grand-daughter seems very happy in it. It is straight forward to fit, albeit I usually have to fiddle around until I get the right angle to clip it to the iso-fix fittings. It sits securely in the car even when my grand-daughter is not using the seat. It is light enough to take in and out of the car and carry into the house without any trouble. To fit it properly I had to remove the head-rest. The instructions are not particularly clear.

    Rated 5 out of 5 by from Perfect Wanted a seat that had great safety results when iso fix is used and when it isn't! Checked the 'Which' reviews and this was the best seat for what we wanted. Really pleased.

    Rated 5 out of 5 by from Really comfortable and simple to use I bought this car seat for my 4 year-old when they had a 20% off promotion so it was a good price. The seat is well-padded and the headrest is a good shape for support and naps on long journeys. We don't have isofix in our current cat so cannot comment on the fixings butbit works well with the seatbelt and my child can reach to buckle himself in. The seat is quite wide at the top, especially with the side impact technology added extra fitted but it seems very safe and we chose it from reading Which reviews for the safety features so we are happy knowing our son is safe.
