The new preservetech secure lock raised Toilet Seat features three locking points on the front and sides for added security and stability. This toilet seat adds an extra 5" of height to the toilet and includes padded armrests that can be adjusted or removed. Most non-permanent raised toilet seats only offer one or two locking points of security resulting in instability when the end user places more weight on one side of the unit. The seat fits on most elongated and standard toilets and installs without tools.
