The first impression when opening the packaging was an intense aroma of fresh pine. Even after several weeks of use of the cushion contents still exudes a fresh wood smell. The cushion is well stocked with chips of stone pine. As can be seen in the accompanying description of the manufacturer, the temporary removal of chips is possibly recommended to change comfort. My wife, who took advantage of for years horsehair is really fond of the Swiss stone pine. She sleeps very well on your pillow. Even after weeks of use changes in shape of the pillow barely recognizable.
