Volvo S80 car seat needed

[trixibellefifi]

Hello, does anyone know of a car seat from birth and from 9 months that will fit in my Volvo S80 please?
I've tried 3 different seats but the seat belt is too short!!

Thank you

The Maxi Cosi CabrioFix fits in ours...

we have maxicosi too, we didn't have isofix points, but had them fitted and it was cheap. Now DD is older and heavier we have a rear-facing seat manufactured by Britax for volvo. It's very safe, but can be slightly challenging to get a wriggly baby into.
