It came in such a small box that I was a little worried. Since this mattress was going to be used upstairs on the top bunk I went ahead and carried the box upstairs. First of all, it was very easy to carry up the stairs and put on the top bunk (that cannot be said for most mattresses). After I rolled it out, it fluffed back up within a minute and looks like a real mattress. It's think, firm, and sleeps well. I'm VERY pleased.
