【COMFORT】 The Airsoft4.5 is a 4.5”-max thick beast of a mattress designed for comfort and comfort only. Lying on it, you can’t feel the ground, even if you are a side sleeper..【QUIET】This insulated mattress is 16lbs in weight, full of high-quality foam. Unlike normal air mattresses, there is no bouncing around for you or your partner when the other turns over or gets off the mattress..【NOTE】The double mattress is large and weighty. Due to that fact, it may take a little bit of effort to deflate, especially for the new camper who has never used a self-inflating mattress before. But please don’t worry, if you follow the instructions and try 2-3 times, then you will master the skill..【SELF-INFLATING】Owing to a patented two-way valve design, inflation can be achieved by simply flipping the valve. This part is much easier to learn than the rolling back part..【SKIN-FRIENDLY】The surface fabric is suitable for direct contact with even sensitive skin..【TESTED R-VALUE & LOAD-BEARING CAPACITY】The industry standard ASTM F3340-18 test R-value is 13, so it provides stronger cold resistance capability. Moreover, the mattress bears a weight of 440lbs, and Airsoft demonstrated no air leakage or damage during 24-hour static pressure tests..【IDEAL CAR CAMPING GEAR】 Highly recommended for car camping and family camping because it does require space for storage. BUT NOT SUITABLE FOR HIKING & BACKPACKING..【LOST HORIZON HIGHLY VALUES CONSUMER EXPERIENCE】Our goal is to create high-quality professional outdoor products for outdoor adventurers, so we attach great importance to your experience and feelings.
