Using this pillow is easy. Just place it on your bed and rest your head on it. For side sleepers, make sure your head fits into the shoulder recess for the best neck support. When it comes to maintenance, the removable 100% Tencel™ fiber cover can be taken off and washed according to the care instructions on the label. Avoid exposing the pillow to direct sunlight for a long time as it may affect the performance of the cooling gel. If the pillow gets dirty, spot - clean it gently with a mild detergent. Keep it in a dry and well - ventilated place when not in use.
