Personally, I do not understand the rave of Memory Foam (shredded) pillows. Being a back and side sleeper, the firmer the pillow - for me - the better I sleep, and I have tried and used many different pillow brands/styles. Yes, the shredded memory foam pillow is comfortable. However, I find that the highest percentage of the time, all NEW pillows perform well for the first couple of nights. Many pillows start to fail around the third night. So far, so good, on the Shredded Memory Foam pillow! Time will tell, though.
