I loved the text from Wayfair, "Enjoy your new toilet seat".  This was my first time to install a toilet seat as a recent widow and I wish Kohler would have included more concise step by step instructions.  I did get the job done and it was a lot easier than I anticipated.  Kohler makes a great product, Wayfair sells them at a reasonable price (I checked 3 sources and they were the best) and the shipping time was amazing.
