I have always been a fan of, and slept on pillows that could be fluffed and flattened, molded and flipped, but over time our sleeping preferences can change. After waking up with neck pain every morning for what seemed like weeks, I wanted to see if changing my pillow would help. I went against my previous pillow loves and decided on the non-fluffable, non-flippable Pure Rest Natural Rubber Contour Pillow. It is a single-sided pillow so it can’t be flipped, but it does have two distinct ends, so it can be rotated. Contour heights are not standard and can vary by model.
