Yep avoid the Purflo, it's too saggy, but it is very easy to wash. I think it's good to regularly be able to clean a baby's mattress. It doesn't trap any dust either. I don't think it will be any good when my daughter is heavier, it will just sag. I can't believe it cost more than our stroller!! Also it's one of those baby purchases that you probably won't be able to shift on ebay as everyone wants new mattresses for their babies. Hopefully I can pass it on to a friend. I think I'll get a Naturalmat, they look really solid and will last until they are much older. If I do get one, I'll let you know. Not likely to buy for a year or so though - will put it on next year's xmas list for the grandparents to buy probably!!
