• QUICK INFLATION: only 1 chamber & 1 layer,inflating much faster and easier than the 2 chambers & 2 layers old version ones;no air pump needed
• LIGHT-WEIGHTED: ripstop parachute nylon fabric, weighs only 1.80 lbs,yet can support up to 400 to 440 lbs;also, can be used as a pool float since it's waterproof
• HEADREST DESIGN: compared with the old version,the headrest design makes it much more comfortable;and the lounger can stay inflated for 4-8 hours
• ANCHOR DESIGN: With an elastic anchor loop sewn in it's corner to allow you to anchor the lounger down in a windy condition, while there's this elastic loop, the anchor doesn't come within package in case it should poke the lounger
• Walking or run fast to capture air and after that, make sure to twist the end at least 3-5 times so the air tightens the lounger; Practice makes perfect, with enough practice, only a few swoops is enough.But if you can't make it anyway, return it for replacement or 100% refund of your purchase price
