Great Pillows
Number of Items: 2
Got the 2pk, while these are probably not worth $65/pillow, they are definitely comfortable and I had no issues sleeping on it. Much better than the memory foam pillows from Walmart.
Could be a bit bigger and denser on the foam, but otherwise its perfect.
Pair with nylon cover for better cooling.

Great Pillow!
Size: King (Pack of 1)
Excellent product. I have been searching for a pillow that wasn't too soft or too hard and supported my neck. I now wake up without a stiff neck and a headache. Wonderful!
