    Very disappointed after reading decent reviews. The pillow itself doesn't have a a well defined shape and is VERY SOFT AND MARSHMALLOW-ish. The pillow cover is cotton knit and isn't thin but doesn't help the pillow to keep its shape. It's approximately 5.5 to 6 inches high.

    So comfortable. I love it. It’s firm and holds its shape, yet it cradles your head, and its soft. It’s wonderful.

    Amazing. The Perfect Pillow for Side Sleepers with neck pain!
    Size: Queen (High Loft), Number of Items: 1
    I do have to update my experience. This still is a very comfortable pillow, it's just I can't sleep with it under my head (it's now my hug pillow). After using for 2 weeks, I developed severe neck spasms. Pillows are very individulized and as it turns out, I probably need a firmer pillow than this "highly" comfortable pillow can offer. Will NOT change my rating. Wow! I'm impressed with this pillow so far. I'm a side sleeper mostly but chose the medium-high loft 6.2" as recommended which was the perfect height. I didn't see any taller options but this has turned out just right. I did hours of research before chosing this product, which turned out to be advantageous. It's not as cooling as my old memory foam pillow with the gel layer but it stays cool long enough that I don't have to move the pillow around to be comfortable before falling asleep. It's surprising lightweight. I like it much more than any memory foam I've ever had. The best news was that within a few days my headaches and neck pain have improved by 80%. I am really very impressed with the quality of this pillow. It is softer than I anticipated but still firm enough to keep my head elevated giving me perfect spine alignment and great support. It truly is the MOST COMFORTABLE supportive Pillow I have ever slept on! The smell is only minor at It's worst and has nearly disappeared after just 4 days. It is a mild latex smell but definitely NOT petroleum. It's in the moderate price range at ~$100 and worth every cent. High value for the price. I really really like this pillow and highly recommend it. Big fan! Might irder a 2nd as a backup if it doesn't last but it's so well made I feel that won't be a problem.
