Did you plop down into your seat all excited to get out and drive your Mini just to find you fall through the bottom of the seat? Yep, it happens to everyone eventually.
 
This wire strapping seat diaphragm is what supports the seat base and is a direct replacement for 1974 to 1992 cars, however it can also be fitted to the earlier 1959-74 Minis as well; as it is a superior upgrade to the original rubber diaphragm. 
 
Supplied with new springs.
