I've made several good purchases at O before but this is a first for reviews b/c I just had to. For years now I have suffered terrible stiff necks and headaches caused by not sleeping right and waking up with all kinds of pain. I used to wake up every morning dreading how bad my neck was going to feel this time! The pillows were delivered in 2-3 business days and I have been sleeping on them now for 4 weeks. Since the first night I got them, I have not had a stiff neck ONCE and the only thing I dread now when I wake up is actually leaving bed. These are by far and away the best purchase I have made in a long time. I felt obligated to say this so that anyone out there who might be sufferering like I was with no solutions in sight...this is IT. Super comfy, a dream to sleep on every night! GET THEM! I am buying 4 more!!
