Built-in Electric Pump for Easy Setup and Space Saving - The double sleeping pad includes a built-in electric pump for one-touch inflation and deflation. Vacuum compression storage saves space. Note: Pump endurance is 20 minutes; inflation takes about 1 minute and deflation about 2 minutes. Please monitor the power level during use. Hi-Tech Memory Foam Sleeping Pad - Self-inflating pad features Hi-Tech memory foam with a density of 26D, higher than typical 16D. High resilience distributes weight evenly and relieves pressure at contact points. You can adjust softness by controlling the inflation time. Ultra-thick Upgrade - Size after inflation: 78" x 51" x 3.1". Larger and thicker than many camping pads on the market. Supports up to 800 lbs and was tested at a static pressure of 800 lbs for 24 hours with no air leakage or damage. The 3.1-inch thickness keeps you above the ground and provides consistent support when you move. Skin-friendly Fabrics - Surface uses outdoor-grade 50D stretch knit fabric that is breathable, sweat-absorbing, heat-insulating, and tear-proof. It is more wear-resistant and elastic than common nylon fabrics. Skin-friendly material is safe for direct contact with sensitive skin, and the knitted fabric is noiseless for a quiet night. All Seasons Insulation - R-value of 9.5 per ASTM standard, providing superb insulation. With moisture-proof and breathable fabric, it helps keep you warm in winter and cool in summer. Because it is all-foam, it weighs 14.8 lbs after storage and is not suitable for backpacking and hiking. It is best suited for car camping, RV travel, or home use. Use scenarios - Car camping or RV trips where quick setup, comfort, and ample space are priority. - Overnight guests at home or in a camping setup that requires a reliable, supportive surface. - Year-round camping in varied conditions, or use as a stationary bed substitute in a cabin or trailer.
