Normally I get invited to get up on the couch only, and only if it has a blanket on it.  I think this has something to do with the amount of fur I leave everywhere, or so I've been told.  This nice comfy chair has been calling my name though, so when I had the opportunity, I went for it.  My human Elise was doing laundry and seemed like she was going to be in there for a while, so I curled up on the chair to take a nap for as long as I could get away with.
