Using this mattress topper is super easy. Just unroll it on your King - sized bed and you're good to go as no assembly is required. When it comes to maintenance, vacuum it regularly to keep it clean. Avoid using harsh chemicals or bleach as it might damage the memory foam. If there are any spills, gently blot the area with a clean, damp cloth. Also, make sure to keep it away from direct sunlight for long periods to prevent the cooling gel from deteriorating. If you notice any signs of wear or damage, contact our customer service for assistance. Enjoy a comfortable and restful sleep with your new mattress topper!
