I absolutely love this pillow. I've had it over 8 months now and it has been so good for my neck! I have neck problems and this is hands down the best pillow I've ever tried! I've had the contour memory foam pillow before and will never go back to that ever!
One of the reasons I bought this pillow because I changed from queen to king size bed. I have queen size foam pillow of different brand and was not able to find the king size for the same brand. I decided to buy this pillow reading all good reviews and it's good price. But The pillow is not as comfortable as I expected it to be. It's pretty thin for me and ultimately I switched to my queen size pillow.
I am pretty frugal and normally don't find it worthwhile to spend more when less will do. That said, a pillow is something I feel it is better to pay a little more for. These pillows are extraordinarily comfortable and I can actually say I have slept better when using one. The king size is nice because it can fit two heads helping to facilitate winter snuggling.
I had high hopes, but alas, this pillow is very hard. There really isn't much to add, except that it is also thin, which is not great for side sleeping. I awoke with a headache both times I tried to sleep on it and changed pillows in the middle of the night. I am giving it 1 star for being a king size. Sorry, I just cannot recommend this pillow. I really hope it is returnable.
Bought this based off product description and other review and I'm far from happy. I'm a side sleeper and this pillow is way to thin to provide me the needed support or comfort. It's not 4" thick, but closer to 2.5" thick. It may be great for back or stomach sleepers.
