I went to shop around and read reviews before I decided to buy the product though I am a  little skeptical if it's shoddy. However, i just give a benefit of the doubt and go ahead to purchase the product. I am not worried if the head and foot part are not yet expanding properly for its just 2-hrs had passed since I opened it. I didn't regret my purchase. The product is of good quality, no smell. In good price and fast delivery.
