@DrDan this is a good (and hard) question! There's not really anything that indicates using a Flash air pad with the Therm-a-Rest Trekker Chair won't work or will cause damage to the pad, although your hesitation is certainly understandable as the Flash pad has so many more distinct air pockets than the Therm-a-Rest pads. We're going to move your question out to the general community in the hopes that someone else out there has tried it and has feedback!
