After carefully reading the instruction, I have repackaged the mattress on the floor of my condo  myself. It was easy, although I am 68 y/o. I left it to inflate for three days, and when it was ready, my friend and I replaced it on the bed. It is a good quality mattress, high enough, so I don't need a spring box, and it's surface feels good for  my back. I am really, highly satisfied with thus purchase, and recommend it.
