Made from durable PVC it weighs about 66 pounds when empty and can be setup with the assistance of a standard air compressor in about 5 minutes. Mesh covered holes allow the Magic Swim to fill with water once it's deployed, but also keep unwanted visitors out, and a semi-rigid floating platform in the center of the pool allows you to stand once it's completely filled with water. ~$2,250 for the large version, and ~$2,440 for the extra-large one.
Just look at that happy couple in the photo. They look like they're having a good time, don't they? Also, like they've been drinking champagne straight from the bottle. Kidding, I know what a guy with two champagne flutes up his ass looks like. This guy (New Years '06).
