Bests & Worsts Reviews from Amazon

I am pregnant and am looking for a mattress topper to help with my hip and back pain. After carefully considering different toppers, I wanted to order this one--mainly because of the reviews and its PURGreen certification. However, after two hours of research it appears that a PURGreen certification (which this company touts) doesn't really exist. Don't believe me? Look it up at: [...] When I looked at the website, I noticed that (unlike a real lab which tests products)there is no contact information about the lab, no location information, no names of products that are certified, etc. So, I looked up the certification company "Polyurethane Alliance." The alliance doesn't exist either. It appears that a mattress topper company created a fake website to make their toppers look like they are safe from harmful chemicals. Buyer beware!
