About this item ?Memory Foam Support?The foam padding of this mattress is double-layered, so it can provide a smart wrapping experience. The top layer of slow-rebound memory foam provides a good balance of pressure distribution between the body and the mattress contact points so as to help the sleeper achieve maximum comfort. The next layer of high-density foam meets the breathability your skin needs and ensures that you stay asleep longer on this mattress. ?Pressure Relief Structure?This mattress uses a two-layer pocket spring structure to better distribute the pressure on the mattress. The upper lower individual springs are not only highly breathable but also highly resilient to protect your body in contact with the mattress from the very first layer. The second layer's higher individual pocket springs work independently of each other to not only reduce the impact of your partner's movement over hills but also support your body evenly and keep your spine aligned throughout the night. ?Breathable Printed Fabric?Full mattress cover is made of a cool knitted fabric with flower stripes, which can not only absorb sweat but also has a soft and comfortable surface. In order to facilitate you to lift the mattress to the bed or turn it over, we also designed a handle on the mattress cover to bring more convenience to your use in daily life. ?Mattress in a Box?: In order to facilitate you to receive the mattress as soon as possible, it is vacuum sealed and neatly rolled in a box.
