There is nothing negative to say. It was carefully delivered and packaged. It was purchased for my son, who has allergies and is sensitive to certain materials/fabrics. He enjoys this topper and sleeps soundly. His old one was fraying and ripping in the back. This is three years old and still feels brand new. It washes well and there are no rips or tears yet. I'm very pleased with my purchase. (I was not compensated for this review; it is simply my honest opinion.)
