We have bought a product that stated it was 100% cotton. It turned out to be 100% polyester. Right now it has almost been 2 months of disillusioned hope and frustration trying to communicate with Amazon to request the refund that A to Z guarantee promises us. It's been an expensive (65 for the matress, 24 for sending it back: the refund has been denied once without them even examining the returned package) and irritating experience. Don't trust the vendors on the website and don't think you'll get your money back easily when scammed!Negative factual reviews don't get published!Vendor : WUXUEHUAProduct : CVNJSKDKH Alto Grado de Hotel Topper Dormir cojínUPDATE : They refunded all the costs after being able to talk to a real person. To find this telephone number, you have to work through a labyrinth of links in the dungeons of their website. The same product is still available on their website! No reviews published!
