This was a perfect online transaction.  We tried to buy two replacement toilets at Home Depot.  All of their options for a one-piece toilet had a back that was too high.  So went to internet.  They are great.  We purchased two. Quick shipping.  FedExp left them at our front door.  The next day the plumbing company came to install.  No issues.  In today's broken world, this was a shocking and pleasant experience.  Thank you. Highly recommend this model and this brand.  And Wayfair.
