Oh my god, this memory foam mattress is awesome. This package was delivered as promised and airtight. When  I open the box ，I saw the mattress was compressed in thick plastic flilm wrap,and I cut off the thick plastic film with the special cutter including the package , then take off the big plastic bag, this 10inchs mattress inflated after 15minutes. This memory foam mattress cove is so soft, and feeling  very comfortable after lying down, it fits the body,. I got long time not sleep well, because my old memory foam mattress was so soft , evry morning I was feeling pain with my whole body. But now I get this mattress, it just like magic, I was sleep very well every night now. Recommend this memory foam mattress.
