Airhawk Cushion Takes Away Road Shock Big-Time!

I have nothing but good to say after 9 months now. 9 hours on this puppy 5 days a week and No Leak. The trick is to not slide off but lift yourself up & down with care(don't slam your butt) when you leave or enter the cab. This cushion is the bomb. Takes away road shock Big-time! I weigh 320lbs my friends(Dam rice cakes are killing me) with a 52" waist-No Lies-just facts my friends. The best coin I ever spent. The material looks as good as when I got it. Trust me my friends-Drop the coin and treat it with care. I'm out !!!!!
