This pillow works! I'm a back sleeper; provides support but is not too high. As a small person the height has been a challenge and I have tried many pillows! No neck pain!
To be honest I regret purchasing these. They were GREAT for the first couple of months, but now they give me neck pain. It's almost as if the foam lost its integrity/support- it 'looks' fine, but doesn't work the same way it initially did. For this price, I expected better. Would not recommend.
If you have shoulder or neck pain, I would not recommend this pillow. It's super comfortable initially, after time it causes intense pain for me, a side sleeper with neck pain. My partner has also expressed discern and stopped using it, he's a back sleeper. It's too hard and doesn't allow the neck the movement it needs, it's also too high for an aligned neck with spine.
