It took two tries but I did find a pillow that works great for me. I gave only 4 stars because my initial order directly with My Pillow took almost a month to get to me. I used their guideline for ordering, and followed the chart which indicated as a small, 5'4", 120 lb person who wears a small sized T-shirt, I should order the second from the bottom pillow loft. It was way too thin and didn't have enough fill to keep my head propped up appropriately. I called and they sent out my free replacement pillow (the next size up for loft, with 30% more fill) and it shipped within a day! Can't figure out why the original order took over three weeks. I got it quickly and it is perfect! The return was easy. I printed the form, packed it up, and shipped it back via USPS. No credit needed, as I was never charged for the replacement. Now on to comfort. I have major neck issues and was waking up every hour. I was using a $100 Tempurpedic pillow but it was too hard. Even my ear would go numb while side sleeping. Then I tried a softer foam pillow that had a rounded edge. Still not perfect and neck pain returned most days. I felt worse when I woke up than when I went to bed. I don't know how they do it, but my the My Pillow technology is a game changer. Clearly it's not just "a bunch of cut up foam" in a case. I have had zero neck pain since using this pillow! Something I never thought possible. And I've tried so many different and very expensive pillows in the past. I haven't changed anything else, so I know this pillow somehow gives me the proper alignment for my neck and back. But, don't necessarily follow their chart when deciding which pillow to order. I needed more fill than my "size" indicated. They let you sleep on it for 30 days, and will replace/exchange it for free, so what's not to like.
