We bought the Cybex Sirona S i-size car seat from Mothercare. I picked it up from the store in Croydon and Hubert fixed it into our car. I highly recommend getting your Isofix car seat fitted whilst you're there, as the staff are very knowledgeable about the whole process and they will ensure that it is fitted properly into your car so your baby will be safe whilst you're driving. Hubert was excellent and very thorough. He made sure that the car seat was fitted properly and then also made sure that I knew how to use it. I put my baby in the car seat whilst Hubert was there so I could ask any questions that I wanted to. My baby loves the car seat, she is very comfy and we love the ease of being able to put her in it as it has the spinning base attached to it. Thank you very much Mothercare and Hubert!
