we just fitted our car seat last weekend in preparation and i swear we nearly got divorced over it. The instructions are so hard to understand. We have a safe and sound. Also what have other people done to stop it moving. We tried to put towels underneath it but it still doesn't seem super secure. I want to get it fitted professionally but my DH is a tight arse. I think he has decided to still try and get it fitted though while i am in hossy cos it just doesn't seem secure even though we installed it exactly as the instructions stated.
