ULTRALIGHT & TRAVEL-FRIENDLY DESIGN: Weighing just 0.35 lbs, this seat cushion folds down to a compact 5.9x3.5 inch size—perfect to slip into your backpack or even a large pocket. When unfolded (15x11x2 inches), it offers ample cushioning for long sits on bleachers, planes, stadiums, or office chairs INFLATABLE SEAT CUSHION: Self-inflates rapidly without a pump for instant comfort. If it fails to inflate automatically after unscrewing the valve, simply blow it up manually to full expansion. Note: Manual inflation may be required for the first use, as the cushion may be compressed during long-distance shipping. Do not over-inflate—this will compromise comfort. After use, open the valve to deflate, then roll it up for compact, hassle-free storage SUPERIOR COMFORT-CUSHION & TRAVEL PILLOW: Use it correctly for optimal comfort and durability. Place the ATEPA logo side—made of soft 30D stretch fabric laminated with TPU—directly against your body and under your hips for gentle, elastic cushioning. Place the non-logo side, crafted from durable 190T pongee laminated with TPU, directly on the ground to provide stable, abrasion-resistant support. The foam-filled core offers balanced cushioning and reliable support. Versatile by design, it also works as a self-inflating outdoor pillow or a comfortable travel pillow for flights, delivering support wherever you need it WIPEABLE & VERSATILE FOR EVERY SCENE: This outdoor-ready seat cushion is water-resistant and can be a thoughtful gift and perfect for stadiums, bleachers, airplanes, camping, hiking, travel, office chairs, concerts, and all outdoor adventures. Works seamlessly on hard seats, wet grass, patio furniture, boats, canoes, and kayaks. Effortless to clean: just wipe with a damp towel FIRST-USE & LEAK-PROOF GUIDE: Open the valve to let the cushion self-inflate. For first use, due to long-term compression, please blow 1–2 breaths to help it fully expand for best comfort. After inflation, tighten the valve completely to prevent air leakage. For small holes or minor tears, use the included 1.97" repair patch to fix easily. If the issue is beyond minor repair, please contact us for a replacement or support
