I bought a kingsize mattress .It comes wrapped up and folded  sideways giving an impression of a twin mattress. It was not in a box and was wrapped in a plastic sturdy cover. I had to search the website to check that there is no size disparity between my order and delivery since it was a 3 feet package. It comes with a cutting tool which works well. The mattress  expands fast after opening the package. It is medium firm and the edges are well supported. Its heavy and will need 2 people to lift and put it on the bed. Satisfied with the quality and comfort.
