Seriously, for those of us who have a problem with heating up and not cooling down easily (no, I'm not joking), I think this sounds fantastic. I mean, have you ever noticed how common it is for there to be one hot person and one cold person in a couple? I'm burning up when my husband is comfortable, then I kick off all the covers and freeze him to death, poor man. It's a sad thing. Something like this might help keep me cooler without him waking up in his sleep from the cold.
