When my mom came home in a wheelchair, we got this to make it easy to negotiate the sliding glass door threshold to the patio. It worked perfectly in Florida's famously wet weather and we loved that there was no assembly and no need to bring it inside or weigh it down for storms. We found it was incredibly useful not just for us, but for friends and neighbors as well. It is heavy, of course, so you'll need able-bodied folks to move it around.
