I ordered 1 blue and 2 white toilet seats. The blue one is just fine. The white have a defect manufacturing. The hinge covers on the white ones to not stay in place. Wayfair sent replacements for the white ones and they still had the same problem. Without being too graphic, when using the white seats, the hinge covers would not stay in place, causing them to open and the toilet seat would slip out of the hinge moving the entire seat. I had to secure the hinge covers by drilling a screw through the hinge. The blue one is designed to snap in place and secure the seat. The white ones need to be the same. Wayfair was very accommodating in replacing the white seats at no cost, but unfortunately the replacements were no better than the originals.
