We hav a non lounger Barefoot Spa and from our experience, it can easily hold 5 adults plus little ones. The cool down seat is a must and really helps. Jets are everywhere. My spa came with a bunch of chemcial sto get started, but it also has an ozone generator, so I havent really used them much. We are inpressed with the cover and the surfaces of the inside of the tub where you sit. We very highly recommend Barefoot Spas.
