Question: How thick is this pillow
Document: For me, it's a huge problem. Will have to return this pillow. My husband is 'considering' returning his for the same reason.
Wonderful. My neck does not hurt and no more headaches. This pillow is amazing! We were given one as a gift and had to have another one.
I bought this pillow for my husband because he has neck problems and he said it really helped him sleep better.
This Pillow has met and exceeded my expectations as a very comfortable and supportive pillow. I would recommend it to anyone and everyone!
Love this pillow! As a side sleeper this pillow supports beautifully. It needs to be broken in like anything else memory foam though.
The pictured pillow is not what came. I am not happy with it but because we used it and tried to like it I have to keep it. I was looking for the pillow with the curve cut out like the picture and did not get it.
There was a shipping mix up with the pillow order I placed and it was handled professionally by the merchant. These pillows come highly recommended by my sister in law and I cannot wait to try them tonight.
These are great pillows. The only thing that keeps them from 5 stars is the length of time it takes to get the awful plasticky factory smell out of the pillow. Its strong enough right out of the box to give you a headache for a couple of days.
I bought this pillow just on a wim, for my husband. This poor man has tried everything to stop his snoring, and although this pillow says nothing about that, he DOESN'T SNORE ANYMORE! I'm serious! I swear by this thing!
It is foam (polyurethane?) so it does hold some heat after some time. If somebody come up with a really 'cool' pillow, that will be great. This is not it. At the same time, it doesn't get too hot as well. Just OK.3. Good for sleeping on your back; not good for side sleepers.3. Price can be a little lower.
Answer: At the highest point at the top of the pillow it is 4 inches. In the curved area it is 3.5 inches. When I press into the center of the pillow to simulate the weight of a head it flattens down to about an inch.
