I had an unusual problem in that due to a design issue my cloakroom toilet seat just would not stay up when the boys used it.

My problem is that due to the tank lid being larger than the tank the seat won't stay up when boys use the toilet. As you may notice the lid has been removed from the toilet seat to reduce the length of Sugru clip that was needed to solve this problem.
