Using your Mila 12-inch twin size memory foam mattress is a breeze. Once it's delivered to your doorstep in the box, simply unbox it and place it on a suitable bed frame. Then, unroll the mattress and let it decompress for up to 36 hours. During this time, it will expand to its full size. As you start using the mattress, you'll notice how it conforms to your body, relieving pressure points and providing a comfortable sleep. For maintenance, it's a good idea to vacuum the breathable stretch knit cover occasionally to keep it clean. Avoid using harsh chemicals or sharp objects on the mattress. If there are any spills, clean them up promptly with a mild detergent and a soft cloth. And remember, the mattress comes with a 10-year warranty, so if you have any issues during this period, reach out to the customer service team.
