I was so excited to have the opportunity to get this toilet.  I have always wanted the type where the plumbing is all hidden within the toilet.  Much easier to clean and it looks very modern.  Then to top it off, the push button flushing system.  The tank itself is half the size of the original toilet.  Talk about saving on water each and every time you flush.  You get absolutely everything you need to install it, all you do is hook up the existing water line, use the enclosed wax ring and bolts, and your in business.  It is elongated as stated, but the back area where you actually sit is a little wider making it seam as if you are sitting on a chair.  Very comfortable.  I couldn't be happier with this toilet.  It completed my bathroom renovation.
