Maclaren twin triumph stroller for a newborn?

I have been given a Maclaren twin triumph stroller. I am due in february when my daughter will be 21 months old. I'm wondering if it will be suitable for my newborn? I know it does fully recline and is meant to take a newborn safely, but on the practical side, how is the newborn strapped in? Is there any kind of carrycot that fits into it? Would it be comfortable?
