Looking for experience with sleep majestic and their shikibutan mattresses

Hey everyone, I'm from prince George and am wondering if anyone has bought one of these mattresses and what everyone's thoughts are? Our purpose for even looking at this style is that we can roll it to store allowing our pet ferrets more usable floor space, and before we make the 10hr trip down to check them out we want to see if anyone has a good experience and if they are comfortable? We would pair it will a thin box spring if needed.
