The Memphis Ultra-Fix® Silentium® soft close seat is designed for universal pans and closes softly, preventing slamming and pinched fingers. Made from American Innova® Generation XXI moulded wood material, this seat is more highly compressed than standard wood, providing a more stylish, thin profile design. The chrome-plated hinges provide a stylish accent for your bathroom and adjust to help achieve the perfect fit to your pan. This seat features Ultra-Fix®: the patented fixing system that always stays tight and takes the guesswork out of installation. The lower portion of the nut shears off when the proper tightness is reached, so you cannot over-tighten.
