An elongated inflatable tubular device which is freely bendable, when inflated, in multiple directions about the longitudinal axis of the device. The device includes an elongated tubular member sealed at each end thereof to form a sealed inflatable air chamber. Spaced apart bendable folds are each formed generally transversely across said tubular member by attachment of one or more opposite points or areas of the side wall of the tubular member along a portion of the length of, and defining each fold. Air within said tubular member is thus free to flow past each fold to balance air pressure within the tubular member during inflation, deflation and bending thereof. The folds are rotationally oriented differently one to another, when viewed along a longitudinal axis of the tubular member, thereby allowing the flotation device to be freely bendable in multiple directions about the longitudinal axis. In the preferred embodiment, the ends of the device are cooperatively shaped, one end thereof having a central aperture formed therethrough sized to pliably receive the other end of the device for releasable retention therebetween and forming the device into a flexible ring.
