Crib Bumpers unsafe?

Lizzie
My mom bought me an adorable chevron bumper a couple of weeks ago. I quickly unwrapped it and put it on the crib, but now I keep seeing stories on Facebook about how unsafe they are!! 
Anyone have ideas on this? Is it maybe safe to use until he starts rolling over?? 
I hope buybuybaby will give me a refund if I decide to return! I have the packaging but not the tags or receipt. Maybe there is a recall on these?
