We had been looking for a replacement seat only the week before but an almost decent one at the sheds was about £40.
Popped down to Netto to look at one - it was either £9.99 or £10.99 can't remember now.
I particularly wanted to inspect the hinge arrangement as we have suffered before with those metal hinges that refuse to stay tightened over prolonged use.
The hinge arrangement was robust and different to the metal ones as was the seat and cover itself. Similar to some £40 seats at the sheds so I bought one.
Once fitted it performed admirably.
And I don't think we will have the wobbly hinge problem in future.
