I ordered 2 of these mattresses.  I was amazed thar they arrived by 10am the next day. I wondered how I would manage them but they arrived in compact boxes. I thought maybe they weren't going to be what I wanted. When we opened the boxes the mattresses were wrapped in plastic. We had to be careful opening the plastic as the mattresses suddenly sprang out of the plastic and looked more like mattresses.  We lied down on the mattresses and found them firm and comfortable. A great buy.
