The Police seat is technically inflatable too. The air bag on it makes a world of difference. I think half my posts in this forum are raving on how much I love my seat.

 

My buddy weighs 375lbs and he rides with the airhawk seat cushion. It has lasted him for several years with no problems. I bought one a couple of years ago, and I never ride without it. It definitely takes care of the numbness issues. The trick is to not over-inflate the cushion. Just a little air works best. I don't think I have had to monkey with the pressure at all since I got the inflation right. Highly recommended.

 

Airhawk for me as well. I like it for two reasons. One it eliminates the pressure points and probably just as important it vents air between it and me. I rarely sweat in the saddle any more and never get "Monkey Butt".
