This square-shaped toilet seat is constructed from durable urea-formaldehyde material that resists scratches, abrasion, and fading over time. The seat measures approximately 17.72 inches in length, 13.78 inches in width, and 1.77 inches in height, with an adjustable installation range to fit most standard toilets with hole distances between 3.93 and 9.45 inches. The quiet-close hinge system allows the lid and seat to lower slowly and gently, preventing loud slamming noises and protecting both the toilet and fingers from accidental impact. Grip-tight seat bumpers are strategically positioned on the underside to provide stability and prevent the seat from shifting during use. The quick-release button design enables you to detach the entire seat from the toilet in seconds for thorough cleaning of hard-to-reach areas. Installation is straightforward with the included quick-attach mounting hardware that secures the seat firmly in place. This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm under Proposition 65. To clean, simply wipe down with mild household cleaners and avoid abrasive materials that could damage the finish.
