I have tried so many different toilet seats over the last few years, Even when buying more expensive seats the same problems kept cropping up with ill fitting fixings. I bought this toilet seat based on the good reviews it already had and it was definitely the right choice. The fittings are perfect, Unlike any other I've come across in my search - It's a hard one to explain, Instead of a nut with washer fastening underneath it has a Long rubber washer with a brass nut running through it, This really keeps the toilet seat in place. The seat itself is plastic, very sturdy and the soft close action is smooth. If you need a toilet seat that doesn't fall off, Has a robust build and you have a girlfriend with a fat arse, then this is the toilet seat for you!
