The only reason this pillow got 4 stars from me instead of 5 is that I have a very sensitive nose and I had to air the pillow out for almost 3 weeks before I could use it. Then I had to not only put the cover it came with back on it, but a waterproof bed bug/dust mite cover and 2 pillow cases. When they say you need to air these pillows out they aren't kidding. However, after waiting all that time, it is now comfortable to sleep on so I guess you can say it was worth the wait. I do have to say it didn't just smell, it stunk! When I took the cover off of it in the hopes it would air out quicker, I had to light scented candles in the room and spray Zero Odor around the room. It was very difficult to go back and check it every few days as the smell was so sickening. Thankfully, I waited it out. If you too have a sensitive sniffer, try and wait it out, it is a comfortable pillow.
