Leo, the woolpad is Snugfleece Original. It is 1-3/4" of pure wool bonded to an all-cotton backing. Very nice, but unfortunately since the wool is bonded in rows, and there's no cover over the wool, it very quickly (w/in 3 months) started to clump into the rows. They say fluff it, air it out, etc. Well that works but only for 1 night, then it clumps again. I can't be pulling the bed apart and fluffing that thing (running fingers through it vigorously, which takes a long time) every single night.
I now sleep on it turned over..on the cotton side, which is slightly nubby but more comfortable than those pointy ruts and clumps on the wool side. I still get hot although not sweaty.
I don't sink into the mattress so that is not why I am hot. My latex topper is not so soft as to allow me to sink in much and the wool topper prevents even more sinking. No, I am hot because of the fabric(s) below me..be it the wool topper, the latex, or something in the mattress top itself. I never had this problem ever on my old Beautyrest mattress.
I may be new to this forum but I am not new to mattress woes.
