Do not put it in the washing machine and stir. - The memory foam pillow cannot be exposed to the sun. It must be kept away from high temperature and fire. Sun or washing will destroy the structure of the memory foam and shorten its service life. Exposure to the sun causes the memory foam material to age and turn yellow. Washing makes the memory foam very heavy, and the water in the pillow core cannot leak dry.. - Keep the memory foam pillows dry at all times and ventilate them regularly. Use a vacuum cleaner to clean the pillow core every month or so or gently tap the pillow core with your hands. If you accidentally get wet, please use a towel to absorb the moisture immediately and place it in a ventilated place. Dry in the shade.. WARM TIPS: Memory foam pillow can only be helpful for improving sleeping quality, cant be used for diagnosis or treatment of any disease (e.g. cervical spondylosis.)
