I was ordering a new mattress and decided on that while I was at it I might as well get new pillows. I had no complaints about my old pillows, thought they were just fine, I was wrong. I received the Casper pillows before my mattress arrived so I slept on them a few night on my old mattress so I know for a fact they were a major improvement. I assumed I had a stiff neck in the morning because I work at a computer all day, NOPE, it was the old pillows and once I started sleeping on these no stiff neck in the mornings! What a difference! Can't recommend them enough!
