Sometimes using a memento or an emote will break it and let you get up. It is annoying though especially with hostiles respawing and you're stuck in a chair or on a bench.

1. If you don't want to use a potion (which one do you use?), or potions and/or emotes don't work, then open the Map and port your character to a Wayshrine -- if the character has at least 149 GP to pay for it. That has always worked for me, and it is the method offered by <F1> Help > Customer Support > Character Stuck. If I recall correctly, accessing the <F1> feature to teleport won't cost any GP.
   
2. Open the Map, select a Homestead which you own, then teleport to it, which should not cost any GP. Leaving the Homestead by teleporting to a Wayshrine any time soon thereafter will cost GP, however. If instead the character exits the Homestead instance into Tamriel, and moves to a Wayshrine, then the character should be able to teleport to any other Wayshrine or Homestead without paying GP.
   
3. If you are a member of a Guild, then you could also presumably open the Guild UI, use the Roster to find the character which owns the Guild Hall, then right-click on the character's name and select "Travel to Primary Residence". That usually does not cost any GP. The costs afterward are the same as porting to or from a Homestead which you own.

Of course, these are just time-consuming work-arounds for errors in the game software that, IMHO, should have been fixed in the next patch after they were reported. However, since there are workarounds, the ZOS developers are not likely to spend the time to make the effort to correct their flaws and errors.

Could someone please fix this? I had to redo a public dungeon because of this. @ZOS_GinaBruno
