Maxi Cosi pebble plus i-size is rated 3.3 out of 5 by 7.
Rated 5 out of 5 by from We love this car seat! Amazed at the negative reviews...wonder if they are in fact about the pebble plus at all? We think this car seat is great. Purchased some time ago and about to use for our newest addition. The inlay is perfect and holds babies in a beautifully laid back position and we never had any problems with the size of the seat at all. We were sad to have to take the inlay out at a few months old (and we don’t have tiny babies!!), and always found the seat to be very well designed in terms of ergonomics and comfort for babies. We had to stop using this at around.17months old and happily moved on to the next stage rear facing maxi cosi seat which goes on the same base. All in all we would give this seat 10 out of 10, one of our best baby purchases and I’m looking forward to using it again!

Rated 5 out of 5 by from Fab Car Seat, Sturdy, Safe and Cosy I am so pleased we bought this car seat (and the isofix base) It feels very secure and sturdy, and the insert was absolutely perfect for my daughter she was born prematurely so it worked as a nest for her when she was small, it was one of the only things that didn't swamp her. She was around 5lbs when we first used it to come home from NICU, and she is now over 11lbs and five months old and we still have the insert in. I think we will need to soon remove it. My only gripe is its a little heavy, and I have a bad back. But I just keep it in the car and take her in and out.

Rated 4 out of 5 by from Great car seat. Loved this car seat. Purchased 2 for my twins. They loved them always looked snug, secure and comfy. Sadly they are 17 mths now so had to go for the next one up.

Rated 2 out of 5 by from Not great for big babies! Initially we were really happy with this... Until my son started growing! We had to take the newborn insert out really early (5/6 weeks) as he didn't fit in it anymore. He's now 3.5 months and just looks so uncomfortable in the car seat. His shoulders always looked squashed and as a result he cries every single car journey. He weighed 16 lbs 10oz and was 65.5cm tall at 12 weeks so is a very big baby! I wish I'd done more research into car seats as we'll be buying a new one soon.

Rated 1 out of 5 by from Way too small I realise most children don’t like the car seat, but this one is just ridiculously small. She looked uncomfortable from day 1, and our baby was small. By the end of month one we couldn’t wait to be able to remove that newborn insert. Her little shoulders were squashed like anything and we had to physically push her in. As soon as she was long enough we removed the insert, only to realise this seat is soooo deep, she looked like her legs were getting pushed up closer to her face. In all honesty, with all the desperate crying she’s been doing when it it, we’ve had to make the decision of taking her out with it as little as possible. And we know it’s not just being in a car seat, because when we used a different one on holiday she hardly ever cried. I now cannot wait to get her to the next car level car seat. And it won’t be a maxi cosi one.

Rated 1 out of 5 by from None Car seat is way too small. My baby is very squashed in It and without insert it's very deep. Very uncomfortable seat. My daughter cries everytime we pit her in. Totally waste of money. Mothercare staff was useless as well.
