Hello Folks , We are about to purchase a new car seat for DD who is aged 2 1/2 she is currently in a 9 month to 4 yr seat, which her 9 month old brother will be going into. We dont want to spend a ludicrous amount on a seat, and have noticed Argos do some cheaper seats made by Baby- start . Does anyone out there have any feedback you can give me about these seats. ie. comfort, ease of fitting and most importantly can a child sleep ok in it ? Any comments welcome.
