Just got our Kiddy Infinity Pro car seat - it is fantastic - DS loves it and I love it because it has won the Which? carseat award the last 2 times for safest FF seat. (RF seats for our DTs won't fit behind my 6ft4 DH in our car).
I wanted to post about the great service I received from Olivers Babycare here. I ordered the seat (for £139.99 plus free postage - best price I could find online) on Monday, had a call on Tuesday asking whether I would be in on Wednesday, because if I was, they would dispatch it. Such a pleasant change for a company to actually care whether or not you are in to receive their delivery!
Anyway, I'm delighted to recommend the company if you're looking for this seat, which I don't think is widely stocked yet.
