This locking raised toilet seat will be a helpful aid for anyone who has difficulty sitting on low toilet seats. It raises your toilet seat by 5 inches which makes it excellent for the elderly or for those recovering from hip leg or knee surgery or injuries. The contoured seat is designed for comfort and the padded armrests support you when you are sitting down and getting up. The front locking bracket secures the seat to most toilet bowls. It can support up to 250 pounds. Please note: this toilet seat riser is meant to lend balance assistance when lowering to and rising from the toilet. It should not be used to bear your entire weight.
