Bests & Worsts Reviews from Amazon

I bought one of these memory foam pillows on 8/11/11 to try out. It was nice and comfortable so I decided to buy two more on 8/18/11. During this time there was a price reduction of about $10.00. The two pillows I received on the later order felt as though the foam wasn't as sturdy and didn't support as well. When I squeezed the pillows they deformed more and went back to their original shape faster than the pillow I bought earlier. I then weighed the first pillow (2 and 3/16 pounds) against the new pillow (1 and 13/16 pounds). The new pillow's foam is 17.15% less dense than the original pillow I received. DON'T BE FOOLED BY THE PREVIOUS POSTERS COMMENTS. THEY WERE FOR THE OLD DENSER PILLOW WHICH IS VERY COMFORTABLE. UPDATE 5/27/13. Not even two years later and the two lighter weight pillows have no support anymore and need to be replaced.
