I have two bikes - one has an elongated brick for a saddle and the other has a supposedly gel-cushioned seat but neither are comfortable. I then found this plump gel saddle cover and what a difference it has made. It has transformed both saddles and made leisure cycling and cycle-touring a pleasure again.
It is far too wide for my elongated-brick saddle but it doesn't matter because the cover bends over and adapts to any shape, padding the areas it's in contact with. The best fit is on my broad ladies gel-cushioned saddle and even though it's still a little large, it simply means I can move it into the best position. It is secured by a drawstring and doesn't move around while in use.
Another benefit is that it also absorbs and cushions the bumps on rough tracks which is especially beneficial on non-suspension bikes which can cause their rider to bounce around painfully on the saddle. Also, in cold weather, it's always warm to sit on too.
My size 14 female bum thinks this is wonderful and highly-recommends it to other leisure-cyclists with a sore bum!
