After giving at least 2 weeks to adjust to the pillow, I can now say I no longer have neck and upper back pain. Advise: dont give up too soon, it takes time to adjust to the pillow and its very awkward when first using it. I promise you'll get used to it and your body will feel so much better waking up in the morning!
My neck and head were not comfortable on this pillow at all. It was like sleeping with your head in a ditch. The pillow is also much smaller than a standard size pillow, so it does not fit well in a pillowcase. It’s also not returnable. All other companies I have purchased pillows from will accept returns on a pillow.
The product is well made but I'm not sure yet if the style works for me as a back sleeper. There are nights when the pillow feels great under my neck and head, and other nights when I wake up with a little neck ache. I'm not sure if it's user error or if I have the wrong size. However, it works great for the nights I want to side sleep. Thankfully, I also have the TEMPUR-Cloud to alternate with.
I bought this pillow to replace my existing Tempur-pedic pillow. I’m not certain what changed, but the pillow I received was not anything like the one I wanted to replace. I don’t know if it’s a different material or filling, but they are just not the same. My old pillow is much heavier and more cushioning. it just doesn’t feel like the Tempur-pedic pillows that I’m used to.
