These pillows were pefect when I first received them. I thought I had finally found a comfortable pillow that will last for years to come. I'm a side sleeper and I got the extra firm. They had a perfect neck fit and was so comfortable....at first. Then, after a year, they are flat as pancakes and so uncomfortable. I wake every morning with neck cramps and stiffness. I can never position them just right for comfort anymore. The pillows don't stand the test of time. Don't waste your time or money on something that you can only enjoy for a little while.
