Using your Gel Dough® + Dual Z™ Gel pillow is a breeze. Just place it on your bed like you would with any other pillow and enjoy a cool and comfortable sleep. To keep it in good shape, avoid sharp objects that could puncture the cover or the pillow itself. If the cover gets dirty, you can remove it and wash it according to the care instructions on the label. For the pillow, try to keep it dry and clean. Don't expose it to extreme heat or cold for a long time as it might affect the performance of the Gel Dough® and Z™ Gel. And remember, this pillow is designed to provide long - lasting comfort, so handle it gently for the best results.
