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. Our air lounger has a patented pillow-shaped headrest design that gives your upper back and neck comfortable support when you need the relaxation most. Our unique patented design together with years of experience in 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. This lazy lounge also comes with a carry bag to let you store and carry the air sofa conveniently, a stake that can be used with a built-in security loop to firmly secure the blow-up couch in a position such that it stays in place even on a windy day, and a BOTTLE OPENER to help you chill anywhere, anytime.
