No more neck pain
Size: Queen(Pack of 2)
I needed new pillows and I’ll be the first to admit that I’m picky about my pillow. I had ordered different ones to try and these were the keepers. They are not too soft nor too firm. I wake up with neck pain and headaches if I don’t have a good pillow. I’m not experiencing any either one now. Make the purchase for yourself and try them.
