I truly wish that these manufactures would take just a tiny card and include installation instructions with the products. I think, its a toilet seat how hard can it be It was difficult! I originally installed it just as you would normally install a toilet seat but being a lift off toilet seat that was not the case. After trying several times to make the seat stay down and not slide around, I finally had to go out onto the internet to discover that there were buttons on the caps that open and close to hold the screw! 2 mins later and it was on correctly. I shouldnt have to rely on the internet for instructions. I would have loved just to a small postcard size illustration to show me how to install. Other than that, I really like the seat.
