there are other things that you could do
1) raise the seat ( easy to do in some cases but not always)
2) put it somewhere else in the car
3) go small and spend more money
your choice really!
( i will always go for the cheap option when i can, call me a cheapskate if u want, but why spend more than you need to ????)
PoD
any more questions that u think i mite be able to help with just ask
