    Rated 5 out of 5 by booster seat I think this is a good value for money booster seat bought to use for my grandson on occasions. 15 September 2016
    Rated 5 out of 5 by Brute X Romer I bought this seat for a 7 year old, It looks smart easy to fit and he really likes it, It's a bit expensive for this age range, But the ISOFIX is what done it for me, No regrets I would recommend. 04 September 2016
    Rated 5 out of 5 by Makes my child happy! Excellent seat! It puts a smile on my little one's face every time we get in. Very pleased! Excellent service from Halfords too. 03 September 2016
    Rated 4 out of 5 by great product brought this for my son as my new car his old seat didn't leave him much leg room. brilliant value you for money, neat and tidy, I love the kidfix stops the seat from moving when he climbs in, only down side I don't feel they tighten enough but that may just be me, when my son is in it and using the seat belt it doesn't move. 16 June 2016
    Rated 5 out of 5 by New seat for my granddaughter I bought this seat as my granddaughter has outgrown the old high back car seats I have. It can adjust to fit her as she grows. I'll be buying another one when my younger granddaughter needs it. 04 July 2016
    Rated 4 out of 5 by Britax Romer Nice seat, isofix compatable. Makes it a lot easier to install and remove when needed. 14 June 2016
    Rated 4 out of 5 by Great comfortable seat Bought for 5yrs old son after mamas ans papas seat recalled. Excellent quality seat very sturdy. Only downside is it is quite wide at top. 31 May 2016
    Rated 4 out of 5 by Great easy to use my son loves it. This high back booster is great my son is only 3 years old. But too tall for the 5 point seats. He had fell asleep in it and because of the funny looking headrest he can lean to one side sat up and has no problem sleeping and no painful necks. The colour of the seat is great and it's really easy to fit with the isofix fixing. On a personal note if placing seat between 2 others the top is wider than the bit where isofix points are which helps when buckling up children. It fits great in middle seat of my grand c4. 09 May 2016
