I got the Deluxe Grand Siberian and it is nicely soft without feeling a bit chunky like some Basic Soft Polyester. Of course being softer it does compress a bit more easily.
If North American stores sold these size body pillows I'd get one of those but nobody seems to make or sell them, so you gotta do what you gotta do. Get it while you can and then you will have it for all your body pillow covers.
Please note that it took nearly a month for it to get to me, but i did get it through regular snail mail.
