I love these! They are awesome for camping, chilling by the pool, when you have grandkids over. If your tall they arent the most comfortable to sleep through the night, but they are perfect for recreational use and for a place for tweens or shorter adults to sleep on and they stash right back into the bag and the closet until the next time.
They fabric is synthetic and has a waffle pattern woven whochI think enforces its ability to keep its shape and not get stretched out. They quickly inflate with a couple of swooshes through the air. It took a few minutes to get the swoosh right. The first few tries werent as effective. I dont know how to explain it, but its really easy once you’ve tried a few different ways.
