I can honestly say that I have not woke up with a sore neck or shoulder since I began sleeping on this pillow 3.5 months ago. It is the perfect amount of firmness and softness for me. I am hoping that it lasts for a year or longer, hence I am only giving it 4 stars for that reason because I want to see how long it lasts. It is a pricey item but if it lasts awhile, I think it will be well worth the money. We’ll see...
My wife and I used to sleep with at least 2 pillows. With these pillows 1 is sufficient. It keeps it's shape much better than others. Fluff it from opposite corners and you're ready for sleep. It surrounds and supports your head and neck throughout the night. This pillow was the perfect match for our Casper Wave mattress.
I love sleeping with the king sized Casper pillow. Previously, I always used to sleep with two pillows so initially I wondered if I needed two. However, one is more than enough. I am a side and back sleeper and it works great for both positions. I would definitely recommend this to anyone who prefers comfort and is okay with spending a little more for a pillow; definitely worth it.
