Just got the Airhawk "medium Cruiser" inflatable seat pad in the mail from the Airhawk Australia online site.

First impressions are good - the ride is much more comfortable.

 

I am still getting the inflation just right so the ride is only going to improve! It should be great for long rides.

 

It only took a couple of days to arrive in the mail (prompt delivery).

 

I am so impressed I am going to get the car version of the cushion for my car.

I've been using one for the long rides over a couple of years and find it very comfortable. I don't think that you'll regret it.
