Royaloak Bamboo Fabric Pack of 1 Ambrosia Memory Foam Orthopedic Wellness Pillow is a specially designed pillow that offers you unmatched wellness and comfort. This pillow comes in a traditional shape to fit standard pillow covers & comes with a bamboo fabric removable zipper cover. We used swiss-ko certified memory foam to provide the best sleeping experience. The orthopedic doctor recommended it as it molds easily and holds its shape to align your head and neck to help relieve pressure points. The odor, if you experience is not harmful but only the fresh smell of new memory foam pillows. The pillows can be easily aired out or kept in the sun to rid of them quickly.
