I've been a fan of air ever since and have used your air cushions cross country two more times as well as up & down the east coast. Nothing like air. Just last week, I took a Medium Cruiser Cushion off the shelf at my store (Black Hills Custom Parts, NJ) and tried it on the seat of my recumbent exercise bike at home. Before that, I couldn't stay on it more than 15-20 minutes my butt hurt so bad. Now, I can stay on as long as my legs hold out. Thanks for a great product. —Ken P., NJ
