The Carbyne Quiet-Close elongated toilet seat is simply elegant. The sleek, organic lines catch your eye and add visual interest without being austere. And for that reason, the Carbyne toilet seat lends itself perfectly to modern bathroom decor where less is more. Manufactured from thermoset plastic—a premium material known for its uncompromising strength and scratch-resistance compared to conventional plastic—this seat is more durable and more streamlined than a conventional toilet seat, and it is geometrically shaped to hide the hinge, adding even more to its uncluttered, contemporary silhouette.
