To use this pillow, simply place it on your bed and adjust it to your comfort. If you have a King or Queen size pillow, you can use the included 2 mL natural lavender oil spritzer to refresh the aroma every now and then. Just give the pillow a light spray. For the best results, keep the pillow in a well - ventilated area. When it comes to cleaning, check the care instructions on the Tencel® mesh cover. Usually, a gentle spot - clean with a mild detergent is recommended. Avoid exposing the pillow to direct sunlight for long periods as it may affect the lavender oil and the foam. Remember, the travel size pillow doesn't have the spritzer, so no need to look for it.
