Me too...I do have a pillow from the stuff, actually two...one inexpensive one which is way too soft, and one that is much tougher, so they're not all equal it seems. However I like neither, I like a regular soft pillow.
I would be interested to try the mattress, but I have some doubts as it seems to me the material might restrict turning around and moving some, and I do, quite a lot....I fear it could feel somewhat limiting or pushing against me when switching sides etc. I have back pains now and then after slipping a disc in '97 when lifting a PA cabinet in awkward position so I need a good bed.
