Material & Design: Shell is non-slip and waterproof 75D polyester pongee coated PVC, and the camping sleeping mat for adults is filled with 19D open-cell foam, soft and comfortable. Diamond-chamber surface design can limit air movement and heat loss for better support and comfort in sleeping. The built-in air pillow can be inflated separately to meet your needs. Self-inflating/deflating: Free-flow and non-leak brass valve, no pump needed. Due to compressed package, the self inflating camping pads and mats needs to be unrolling for 24 hours with valve open when you receive it. For the first time to use, keep it self-inflating for 1 hour and blow it up with 3-5 breathes by mouth to achieve the described thickness before use. It will be self-inflating completely within 10 minutes from second time in use. 12-hour Leakage Testing: All of our self inflating camping air mattresses are shipped out after 12 hours of leakage testing in deflating condition
