The Locking Raised Toilet Seat is designed for individuals who have difficulty sitting down or standing up from the toilet. The seat adds 5” to the height of your toilet seat. The arms can be removed or added tool-free. The heavy-duty molded plastic construction provides strength and durability for everyday use. The improved locking device is engineered with a larger, heavy-duty “worm screw” and locking plate to ensure a safe, secure fit.
