Out of the package, the pillow had a bit of an odor. I let it sit in another bedroom for a couple days and it's been fine ever since (I have bad allergies, so I would have been bothered if the smell were still there). The cover washed and dried up great. It's not any more difficult to put on than a pillowcase on a regular pillow. I just wish I could buy extra covers for it. I thought it would feel awkward to sleep with (I use another pillow on top of this wedge), but I got used to it immediately. I recently travelled and forgot to take it with me. What a difference. I guess I didn't realize how much I like/need this wedge. I've had NO stomach problems since I've been using it. My lower back pain has disappeared also (I didn't realize this until my trip, when my lower back started to ache in the morning; now that I'm home, I'm back to normal in the morning again).
