A toilet seat is a hinged, removable part of a toilet that provides a comfortable surface for sitting. It is typically made of materials like plastic or wood and comes in various shapes and sizes to fit different toilet bowls. The seat usually has a lid that can be closed when the toilet is not in use, helping to maintain hygiene and aesthetics in the bathroom. Toilet seats often feature additional elements such as soft-close mechanisms, which prevent slamming, and quick-release hinges for easy cleaning. They can also come in various colors and designs, allowing for customization to match the bathroom decor.
