I bought this pad with the hopes that it would cool down my foam memory mattress.  I had  purchased a thing mattress pad and put it on, but I always woke up drenched and hot. (Gross, I know)  This has helped tremendously!  It is very thick, and very soft.   I have not washed it, so can't speak to how well it holds up in the wash.  It's a very nice pad.  I would purchase again.
