This toilet seat is 3 inches high, about 2 3/4 inches above a standard seat, just enough to help my husband get up fairly easily from a higher than standard toilet.  It is lightweight, seems fairly strong, and is fairly easy to install.  So far, we appreciate its effectiveness.  We've used one for about a month now.  We were pleased enough to order one for another toilet, which could use the extra boost, as the toilet is standard height.  We hope it will be enough to aid him to get up off this throne, as well.
