Using the CarbonCool® LT + OmniPhase® Cooling Mattress Topper is a breeze. Just place it on top of your mattress, and you're ready to enjoy a cooler and more comfortable sleep. Remember, make sure the non - slip bottom is in contact with the mattress to keep it firmly in place. For maintenance, you can spot - clean the IceTech™ cover with a mild detergent and a soft cloth when needed. Avoid using harsh chemicals or abrasive materials as they may damage the cover. Also, it's a good idea to air out the topper occasionally to keep it fresh. If you have any questions or notice any issues, don't hesitate to reach out to our customer service team.
