BIOS Raised Toilet Seat with Arms 4.5"

My mother has one toilet seat with this toilet seat and another where the rails are separate from the seat. What she likes about this one is that it feels a lot sturdier than the other toilet seat where the rails are separate. I would recommend this seat for someone who needs strong support to sit down and get up from the toilet. It is also very easy to install (no tools required).

The only negative aspect to this seat is that it does not allow for the original toilet seat to be used, and it is not easy to clean between the raised seat and the actual toilet.
