I was about to go on a short holiday to France when I realised my seat webbing had collapsed. With no time to get a replacement, and not wanting to be uncomfortable, I took out the seat and lashed a load of 2mm strimmer filament back and forth between the seat rails, thinking it would do until I could get round to replacing it properly. That was in 2005, so I'm thinking it's about time I did a proper job of it.
