Is it just me? Every case I've got (lots) closes down and presses on the bridge 24/7. I never store a guitar in a case for this reason. The down pressure of the strings is already putting a 6-12 lbs continuously on the top. My cases add another 1-4 lbs of pressure on to that. Why?
If the case is adding pressure to the bridge - top, what happens when a bad move or unlucky smack hits the top of the case and immediate transfers the force through the bridge? Loose braces! Cracked tops. The energy is directed to the bridge and has to go somewhere. I can just hear the thoughts of 100 guitarists tonight: "What's this top crack, I always keep it in the case! Must be when my buddy was playing it!"
This doesn't happen to me because I only use gig bags and move carefully.
Storing guitars for me means keeping em all hung up, and the cases just rot in another non-humidity controlled part of my basement. What a waste of space. Instead of room for 15 guitars I make room for 30. What a design oversite!
The guitar top should only be contacted and padded around the perimeter of the top (and back for that matter) where the strength is very good.
If you look inside the top of most any open case, there's the imprint of the bridge and strings embossed in the damn padding or if there's hard foam there's the image of the bridge, having eaten through the fake fur of an otherwise smooth and perfectly good piece of foam! Who designs these things?
It must be me, cause its been this way forever, and I've never heard a peep from anyone else.
Maybe some bourbon would help, but cases could easily protect guitars well and not just the sides and necks.
