Hey guys, I've gotten this great deal, £20 for a chicco next to me crib. In perfect condition. I'm aware to never use a second hand mattress, so I go on the website to see that a replacement chicco mattress is £60! I've seen a few on Amazon, that say made for Chicco beds, for £15. They say they follow British standards, but is it still safe to buy a third party mattress? If there's even a slight safety issue, I will just save up for a chicco mattress, I was just hoping some other mothers haven't had any issues and been able to save a few pennies. Thanks
