Received this item today and installed on my master bathroom toilet to test fit and well almost wanted to leave on based on it fit perfect and looked nice.  Installing was nice being it gave me options on mounting technique.  I chose mounting from toponlyas I really do not bend and get down low like I used to. So really appreciated this option. Gave you the hardware to do both options as the other was standard installand that requires installing nuts o bolts from beneath and under toilet.  Over all I really like this seat and the shape is to me any how just right.   So , overall totally happy with this item and look forward to installing again when I get my new toiletfor the other bathroom. [This review was collected as part of a promotion.]
