Specific human toilet furniture exists for use in the act. Human toilet furniture has some resemblance to smotherboxes and other queening stools used in face sitting. Human toilet furniture has often a different look. A standard toilet seat may be used as a psychological hint for the intended use. While human toilet furniture with a low upper deck can be very similar to a queening stool, the height of the deck varies more widely. Thus two human toilet-users' body parts may not even touch, whereas such physical connexion is required for a queening stool.
