Well, does that fact that I'm going to buy four more say anything? They definitely STINK for the first week. You need to let them air out standing up and every day or so, squeeze them, shake them, get the air moving through them. But once you've done that, put your head down and get ready for a great night's sleep. You don't even realize you're falling asleep, you just do. Shared one of mine with a house guest when they were here. Same thing happened. That's why I'm buying two for each of the guest rooms.
