Abstract: A universal, convertible, padded end cap for a water bed railing permits the joining of a supplementary end rail to any of a number of available padded water bed side rail designs providing in each case a smooth, decorative, functional corner joint and seal. This cap has significant strength for retaining the rails in a rigidly locked position relative to one another during use of the bed, resisting the forces imposed by persons climbing into and out of the bed across the padded rails; it also provides a decorative and pleasing appearance, matching that of the end rails used. The cap, which is included with the padded end rail in construction, is a mitered, sewn fabric extension from a padded end rail, being designed to match in appearance the end rail the side rails being sealed to the side rails by using a series of sequence of fasteners, which, together with the overall cut of the convertible cap, creates a tight, secure, yet flexible continuous corner joint between the side and end rails.
