We have gone for a travel system from mamas and papas, so we have the whole pram and car seat etc in a bundle, found the staff really helpful when choosing the car seat and iso fix to go with it so yes I would recommend there :)
Mothercare have a specialist who works in-store & provides you with the information on car seats & prams; lets you try them out & see it fits in your car. Plus you get loads of Boots points to use when you purchase 🫶🏻
You can buy online directly from manufacturers such as Joie or Cosatto. That's what we've done both for our first and this time x
Maxi cosi have a sale on, and some car seats attach to prams etc. i looked around online and plan on buying from the manufacturer
It worth researching the safest ones and seeing where they are available.
Mamas and papas
I would recommend mamas and papas we have brought our pram there and it’s a bundle so the cat seat and the iso base are included. They currently have a sale on until the 19th and when you spend so much you get a gift voucher. You can book a free appointment with them and there’s no pressure to buy
We got a Joie 360 ISpin from Halfords
I bought mine in the boxing day sale at newbie and me
Mama and papas is good and also some big boots stores sell car seats x
