Airhawk Seat Cushion, never used. This is the most comfortable riding cushion you can find. I won't go into all the details, just Google "Airhawk Seat Cushion" and you'll find many detailed reviews explaining its special features. Here are a few links: http://www.therohostore.com/Products/AIRHAWK-Seat-Cushion---Cruiser-Pillion-Seating-System-wCover__CRUISERPILLION.aspx http://www.airhawkguy.com.au/airhawk-cushion.htm I'm selling the small pillion seat: Dimensions: 11" Deep x 9" Wide (28cm x 23cm). This one is designed for the pillion rider on cruisers, but it also fits beautifully as the rider seat on sport bikes and scooters. It retails for $169.95 (5500 Baht), not including shipping to Thailand. I'm selling for 3000 Baht. Here are some more pics. PM me if interested.
