【High-Elastic Sponge & Self-Inflating】This air mat is filled with a high-elastic sponge in the middle and inflates automatically in about 2-3 minutes just by opening the top valve, making it easy to set up. 【With Pillow & More Comfortable】The integrated design with a pillow keeps the natural shape of your neck and allows you to sleep comfortably. The thickness is about 3cm, which reduces the unevenness from the ground and cuts off the cold air, allowing you to sleep comfortably. 【Pressure Distribution & Excellent Material】This inflatable mat adopts a pressure distribution design, providing maximum comfort according to the movement of your body. Also, the surface is made of 150D Oxford composite material, which is excellent in both waterproofness and durability. 【Active in Various Situations】It can be used in various outdoor scenes such as car camping, office breaks, parks, gardens, camping, and sandy beaches. Even at home, you can sleep comfortably by laying it under a sleeping bag or on the floor without using a bed, and it can also be used as a spare bed for sudden guests. 【Product Specifications】 Size when in use: Approximately 183 x 51 x 3cm thick Size when stored: Approximately 17 x 29cm in diameter Weight: Approximately 1.2kg Accessories: Storage case Material: Polyester, PVC, Polyurethane foam Color: Olive Purchase price: 7,090 yen 【Please Note】The product is vacuum-compressed for shipping, so please follow the steps below to inflate the air mat before using it for the first time: 1. Open the valve and let the mat naturally inflate. During this process, lightly tap the product by hand to promote air circulation. 2. When you feel that air is entering the mat, close the valve. 3. Push the areas with a lot of air into the areas without air, ensuring that the air is distributed more evenly throughout the mat. 4. If the mat appears to have a relatively even air distribution, open the valve and continue to inflate. 5. When inflating, continue to lightly tap the product to assist with air filling until it naturally reaches the maximum air filling point. 6. If the mat is not inflated enough, add air manually until it is fully inflated.
