Tim...I'm impressed with your list!
I can't sleep on tempur foam because it becomes "hot" HOT and body heat builds up. I had one before, and thinking I was buying one free of it, it seems the top layer of this new one has the same, and I wake up in a heat sweat!
My "worth the money" right now are plants for garden and landscaping as well as the old standy: art supplies!
