Comfortable Accessibility Features a gently contoured surface for extra comfort and slopes down slightly from the back to the front for easier adjustments. A large rear cut-out gives clearance for the coccyx and combined with the gentle downward slope of the seat, fosters rear personal hygiene and an expansive front cut-out. Superior Design Two L-shaped molded plastic brackets have bonded non-slip rubber buffers to keep the toilet firmly in place. The brackets are easily adjusted to fit most toilet shapes and sizes using two large, fluted turning knobs, making fitting and removing the seat quick and easy. No front bracket or front-turning knob to avoid snagging skin or clothes.
