Top priority for our 4.5" Raised Toilet Seat is seat security. Our patented Dual Lock Security, two independent locking systems, ensures that the seat will not wiggle or loosen with use. The seat is great for temporary use; when you need a taller, raised seat; or when a well-secured, cost-effective raised seat is the solution. Comes with weight-bearing Support Arms. Seat weight limit: 300 lbs.
