The same is true for door frame seals and trunk seals. All spend a lot more time closed than open--even more so than the top. Given regular care, none of those collapse from spending more time crushed than expanded. The top seals should be no different: Opening the top periodically to lubricate/protect the seals should be more than sufficient to keep them from taking a "set."
