Wekapo Inflatable Lounger Air Sofa Hammock-Portable, Waterproof, And Anti-Air 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. CARRY BAG, STAKE OPENER ? 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 to firmly secure the blow up couch in position so it stays in place even on a windy day. 100% RISK-FREE SATISFACTION GUARANTEE ?
