✔EASY INFLATION-No pump required. Just whisk it through the air to inflate. The little trick is that you need to trap air by closing the sleeve opening before the end of each movement, and keep the mouth closed until you begin the next movement. ✔ UNIQUE PILLOW SHAPED HEADREST DESIGN- WEKAPO air lounger has patented pillow shaped headrest design that gives your upper back and neck comfortable support when you need relaxation most. ✔ ANTI-DEFLATION TECHNOLOGY-Our unique patented design together with years of experience of making inflated products make sure that once WEKAPO air lounge is inflated, it will stay inflated for at least 5-6 hours for our dear customers to enjoy.
