OK, so I'm browsing baby websites as we're expecting no.3 in March and whilst I think at the mo we'll get three car seats across our 5er touring, I'm not 100% sure yet.

Well, I've come across this new type of seat which allows you to have up to 4 kids across the back of a standard car and wondered if anyone had seen / heard of / tried one of these.

They're called a Multimac - see more here: http://www.multimac.co.uk/home
