This is not what I was expecting, it doesn't use an air pump, or even have a manual nozzle to use. I tried indoors to air it up, I couldn't get it to work that way. I took it outside in a breeze and it worked as instructed. It came with a spike you can use to secure it to the ground which is how I knew which way was up and that worked so much better. Used the wrong side up you didn't have the full cushioning effect and that made all the difference, very relaxing, as advertised. It had the effect of being in a hammock and I like it, so easy and convenient.
I plan on taking this with me a lot of places, it folds up simply and easy to put away in the carrying case. It isn't too hard to get out of unless there isn't enough air in it, there has to be enough air to get the full effect. I live in an area where getting a breeze isn't too much of a problem. I would have never considered purchasing this; but the ease and convenience this will be something I will be sure to have with me, it will be very usseful.
This is unique and original product and it is a novelty that has a lot of uses. It holds the air quite awhile, 5+ hours, which will make for relaxing days, even indoors you can kick back and take a break.
