On April 23, 2017 I purchased four SmartSilk Pillows, comfort level 4. I tried them for a month and woke up with a migraine every morning. When I called to complain, they suggested level 3, wanted to ship back the level 4 but the shipping was too high, so I kept them. I tried level 3 and I still get migraines every time I sleep, they actually told me I am sleeping wrong on them (really)! So I am stuck with eight horrible pillows. What bothers me is the false advertising I hear almost daily, how wonderful them pillows are. I would not recommend them to my enemy. Just think of silk nice and soft, but those pillows feel hard.
Bottom Line: No, I would not recommend this to a friend
