Those things. They're round, and inflatable. Usually most people don't own them, people rent them if/when they go swimming. they have black handles, and seat either 1 or 2 people. (sometimes on the 2 person ones people try to seat more anyways) The one person ones look like a floating donut, almost.
Its for a story I'm writing, and I can't for the life of me think of what their called.
