I purchased this by mistake and am now selling it. It feels great when used for stiff necks. This is a Wawalag neck pillow, ergonomically designed to perfectly fit the curve of your neck. Unlike hard polyurethane foam neck pillows, it's gentle on your neck thanks to its low-rebound, memory foam construction. Your neck naturally stretches with the weight of your head, allowing for a comfortable stretch. The soft pillow cover is removable and washable.
