Until very recently I worked for an office furniture manufacturer: we would occasionally get customers specifying memory foam (ex C-Tech, a.k.a. Vita Foam). Because I could, I used to test fly their chairs to see what the big noise is about memory foam: basically, when you sit on it it disappears. It is the damndest stuff to carry if you pick up a bundle to move it anywhere. It shrinks to nothing wherever you grab it, and kind of oozes out of your hands.When you sit on it, it moulds right up to you like marshmallow: you would want to be in an office with aircon, because it's really familiar with your body parts in hot weather.I couldn't understand what the supposed advantage of it was, neither could any of the upholsterers, neither could our designer.So it's good stuff on bike seats? Could be, the designer pedalled a Harley, so what would he know about motorcycles? (A Harley riding designer is surely an oxymoron?)
This is what I use. And yes I know the bike is still in the garage 😳 Phil
