I have a 30 inch inseam - so my legs are short. With the stock seat I kept slipping forward and did not at all like the seat; however, with my Airhawk I now stay back on the seat with no effort on my legs to do so. Here is what happens (with me anyway). The Airhawk is pushed flush with the backrest; however, when you sit on it it your backside squeezes the air towards the front - so in effect it builds up a bit of an air-rubber bridge that helps me stay on the seat. The height that it raises me up overall is minimal. There are two big advantages of an Airhawk: 1) it cushions you from road shocks which makes me feel sooooo much better after 8hours in the saddle; and 2) it reduces wear and tear on your body parts (spine, legs, feet, you name it) by adding some more cushion between you and all of the road shocks. While some may think this is great for old men (like me!) but in reality it helps to keep each of us from prematurely feeling like old men. Most of us are into enjoying riding as long as possible - and more cushioning helps us each to achieve that objective. The Airhawk guarantee is that they will take it back and refund your money if you do not like it - so you really have nothing to lose by trying it. They sell for about $130 online - no tax/shipping. I often lend my Airhawk to another rider to try out during group rides - resulting in about 1 convert a week. I don't strap the Airhawk down as there is ample friction to keep it from sliding on the seat. With it the slippery seat syndrome has disappeared. Suggest that you try for a fix that does not involve cutting any cushioning out - at least not until you have tried some other options.
