I used this for a two-night camping trip. Product Information The 8cm-thick, low-resilience, wave-shaped urethane foam eliminates unevenness in the car and bumps on the campsite ground, significantly reducing the burden on the body and leading to comfortable sleep. Feature 1: 8cm Thick Low-Resilience Urethane Mat We've adopted 8cm urethane foam, which strikes a good balance between portability and comfort, unlike 5cm or 10cm. The thickness reduces the burden on the lower back and back, and makes it difficult for heat from the ground in summer and cold air in winter to pass through. Feature 2: VENTLAX's Unique Wave-Shaped Urethane Material By using 8cm thick wave-shaped urethane, body pressure is distributed and the body is firmly supported. In addition, the wave-shaped urethane creates a layer of air, which can be expected to have the effect of keeping you cool in the summer and warm in the winter. Feature 3: Quick Setup in Just 3 Minutes Equipped with two large air valves, it automatically inflates in just about 3 minutes. *It may be difficult to inflate in cold weather. In that case, please add air by exhaling, etc. Overfilling may cause damage, so please be careful. Feature 4: High Stain Resistance Even if it gets dirty, you can remove the dirt by wiping it with a wet towel. Feature 5: Button Connection for Families and Car Camping By connecting multiple mats with buttons, you can use them without the mats shifting, even for family camping or car camping. Feature 6: Lightweight and Compact Storage Size The storage size is 60cm x 20cm x 20cm, and the weight is 2.5kg, a lightweight and compact design. You can take it with you without taking up much space, even for camping where loading capacity is limited, such as in a kei car. 【Size】 ・Expanded size: Approximately 190cm x 63cm x 8cm ・Foam size: Approximately 180cm x 58cm x 8cm ・Storage size: Approximately 60cm x 20cm x 20cm ・Weight: Approximately 2.5kg
