Ok, I'm conflicted. I went back and forth to begin with and finally decided I was not going to get a second hand mattress off of Craigslist just because I was tempted by the low prices. Then after putting our crib together I mentioned on FB that next up was getting a mattress. Well, a former coworker piped up that we could HAVE her son's old mattress. I know this lady can be pretty maticulous with her things but her son is in first grade so the mattress is also rather old. I hate to turn down something FREE and don't want to sound unappreciative but just don't know about getting a mattress that is not only used but is around seven years old too. It's an Evenflo Baby Regal if that helps at all.
