A couple of my pillows were to the point where when you took off the pillow case you wanted to put a new one right back on before it touched and infected anything. Pretty bad. So at the big box bulk item store the other day they had two packs of memory foam pillows, going for just a couple dollars more than the regular kind. Thinking "what the heck," picked up a pack of them.
Wow. Very comfortable. Very good investment. If you ever find yourself needing a new pillow, and don't mind looking forward every day to going to sleep, I highly recommend trying it out.
